Features

  • Collimated or Adjustable-Focus Laser Modules
  • Compact Ø8 mm or Ø11 mm Housing Makes these Modules Ideal as Alignment Lasers
  • Lasing at Wavelengths from 405 nm to 980 nm (See Table to the Right)
    • Four 635 nm Wavelength Options Provide Alternatives to HeNe Lasers
  • Single-Wavelength VCSEL Collimated Laser Module for 850 nm Available
  • Round or Elliptical Beam Profile Options
  • Constant Power Mode Operation Using Built-In Photodiode Feedback
  • Accessories to Power and Mount the Laser Modules Available Below

Thorlabs' Laser Modules are available in either collimated or adjustable-focus varieties and provide output powers ranging from 0.85 mW to 4.5 mW (laser safety Class 2 or 3R depending on the model). Each module has an output beam shape that is either elliptical or round, as indicated in the tables below. These modules, which offer single-spatial-mode output and a compact cylindrical housing, are ideal for use as alignment lasers in optical systems.

For single-frequency applications, our collimated 850 nm VCSEL Module produces a single-wavelength output and a round, Gaussian beam shape similar to that of a point source. Its narrow linewidth produces a spectra that contains no sidebands, but this comes at the expense of a lower total power output.

All CPS laser modules are driven in constant-power mode, with feedback from an internal photodiode used to maintain the optical output power. As these products are not thermally stabilized, their optical output power may fluctuate slightly during operation.

Power Supply Options
Each module requires a 5 VDC power supply (not included) to operate. We offer the CPS1 External Battery Pack as well as the LDS5 Wall Adapter below. The CPS laser modules connect directly to the output of the LDS5 adapter, while the external battery pack requires the use of a USB-to-phono plug, which is included with each CPS1 battery pack.

Portable 5 V Battery Pack Available

Alternatively, a male 2.5 mm phono plug is included with each CPS laser module for customers who wish to wire their own power supply. These modules have either an 18" (457 mm) or 24" (610 mm) long cable with a female 2.5 mm phono socket for connection to a power supply.

Mounting Options
The Ø8 mm and Ø11 mm housings are compatible with our line of optomechanical components through the use of various mounting adapters, as shown in the images above. Depending on the adapter chosen, these laser modules can be directly mounted into either internally SM1-threaded (1.035"-40) components or mechanics with a Ø1" bore. Further details on each adapter and its compatibility with our line of optomechanics can be found below.

Thorlabs also offers a Mini-Series kinematic mount for Ø11 mm laser modules. This kinematic mount is among our smallest kinematic mounts available and features 4-40 (M3) taps for mounting onto our Ø6 mm Mini-Series posts.

In addition, we offer mounting kits - which include a KM100T kinematic mount, post, post holder, base, and 5 VDC power supply - for an all-in-one mounting solution for these modules. Please note that the knurled knob used for focus adjustment on the CPS635F, CPS650F, and CPS670F laser modules is too large for the mounting adapter bore. This knob can be unthreaded to mount the diode module in the same manner as the collimated versions. Make sure to loosen the setscrews locking the knob in place before unthreading; not doing so can damage the threading. Alternatively, the module can be mounted by threading the cord and phono plug through the adapter first.

Laser Safety and Classification

Safe practices and proper usage of safety equipment should be taken into consideration when operating lasers. The eye is susceptible to injury, even from very low levels of laser light. Thorlabs offers a range of laser safety accessories that can be used to reduce the risk of accidents or injuries. Laser emission in the visible and near infrared spectral ranges has the greatest potential for retinal injury, as the cornea and lens are transparent to those wavelengths, and the lens can focus the laser energy onto the retina. 

Laser Glasses Blackout Materials Enclosure Systems
Laser Viewing Cards Alignment Tools Shutter and Controllers
Laser Safety Signs

Safe Practices and Light Safety Accessories

  • Thorlabs recommends the use of safety eyewear whenever working with laser beams with non-negligible powers (i.e., > Class 1) since metallic tools such as screwdrivers can accidentally redirect a beam.
  • Laser goggles designed for specific wavelengths should be clearly available near laser setups to protect the wearer from unintentional laser reflections.
  • Goggles are marked with the wavelength range over which protection is afforded and the minimum optical density within that range.
  • Blackout Materials can prevent direct or reflected light from leaving the experimental setup area.
  • Thorlabs' Enclosure Systems can be used to contain optical setups to isolate or minimize laser hazards.
  • A fiber-pigtailed laser should always be turned off before connecting it to or disconnecting it from another fiber, especially when the laser is at power levels above 10 mW.
  • All beams should be terminated at the edge of the table, and laboratory doors should be closed whenever a laser is in use.
  • Do not place laser beams at eye level.
  • Carry out experiments on an optical table such that all laser beams travel horizontally.
  • Remove unnecessary reflective items such as reflective jewelry (e.g., rings, watches, etc.) while working near the beam path.
  • Be aware that lenses and other optical devices may reflect a portion of the incident beam from the front or rear surface.
  • Operate a laser at the minimum power necessary for any operation.
  • If possible, reduce the output power of a laser during alignment procedures.
  • Use beam shutters and filters to reduce the beam power.
  • Post appropriate warning signs or labels near laser setups or rooms.
  • Use a laser sign with a lightbox if operating Class 3R or 4 lasers (i.e., lasers requiring the use of a safety interlock).
  • Do not use Laser Viewing Cards in place of a proper Beam Trap.

 

Laser Classification

Lasers are categorized into different classes according to their ability to cause eye and other damage. The International Electrotechnical Commission (IEC) is a global organization that prepares and publishes international standards for all electrical, electronic, and related technologies. The IEC document 60825-1 outlines the safety of laser products. A description of each class of laser is given below:

Class Description Warning Label
1 This class of laser is safe under all conditions of normal use, including use with optical instruments for intrabeam viewing. Lasers in this class do not emit radiation at levels that may cause injury during normal operation, and therefore the maximum permissible exposure (MPE) cannot be exceeded. Class 1 lasers can also include enclosed, high-power lasers where exposure to the radiation is not possible without opening or shutting down the laser.  Class 1
1M Class 1M lasers are safe except when used in conjunction with optical components such as telescopes and microscopes. Lasers belonging to this class emit large-diameter or divergent beams, and the MPE cannot normally be exceeded unless focusing or imaging optics are used to narrow the beam. However, if the beam is refocused, the hazard may be increased and the class may be changed accordingly.  Class 1M
2 Class 2 lasers, which are limited to 1 mW of visible continuous-wave radiation, are safe because the blink reflex will limit the exposure in the eye to 0.25 seconds. This category only applies to visible radiation (400 - 700 nm).  Class 2
2M Because of the blink reflex, this class of laser is classified as safe as long as the beam is not viewed through optical instruments. This laser class also applies to larger-diameter or diverging laser beams.  Class 2M
3R Lasers in this class are considered safe as long as they are handled with restricted beam viewing. The MPE can be exceeded with this class of laser, however, this presents a low risk level to injury. Visible, continuous-wave lasers are limited to 5 mW of output power in this class.  Class 3R
3B Class 3B lasers are hazardous to the eye if exposed directly. However, diffuse reflections are not harmful. Safe handling of devices in this class includes wearing protective eyewear where direct viewing of the laser beam may occur. In addition, laser safety signs lightboxes should be used with lasers that require a safety interlock so that the laser cannot be used without the safety light turning on. Class-3B lasers must be equipped with a key switch and a safety interlock.  Class 3B
4 This class of laser may cause damage to the skin, and also to the eye, even from the viewing of diffuse reflections. These hazards may also apply to indirect or non-specular reflections of the beam, even from apparently matte surfaces. Great care must be taken when handling these lasers. They also represent a fire risk, because they may ignite combustible material. Class 4 lasers must be equipped with a key switch and a safety interlock.  Class 4
All class 2 lasers (and higher) must display, in addition to the corresponding sign above, this triangular warning sign  Warning Symbol

Hi, We have a CPS532 laser diode module that we are incorporating into our microscope. We have the LDS5 power supply and that works great, but we are integrating all the electronics and power for them into one area and would like to use a different power supply. I was wondering if you give me more information about the power requirements for the CPS532. Does the power supply for the laser diode need to be current controlled or just voltage regulated? Does the laser diode have internal circuitry that regulates to voltage or current? How much power regulation is required to maintain a constant steady output? Etc.
wskopalik  (posted 2019-04-30 04:17:30.0)
This is a response from Wolfgang at Thorlabs. Thank you very much for your inquiry! The CPS532 needs a DC operating voltage of 5V which can e.g. be supplied by the LDS5/LDS5-EC or by the CPS1 battery pack. Other DC voltage sources with a flat 5V output voltage would of course work as well. The flatter and more constant the supplied voltage is, the more stable the laser will work. The CPS laser diode modules are internally operated in constant-power mode, i.e. you have a feedback from an internal photodiode which is used to maintain the optical output power. These diodes are however not thermally stabilized, so their optical output power may fluctuate slightly during operation. I will contact you directly to provide further assistance.

We would like yo know the spatial coherence length of the CPS module. There is several posts asking this question but never an answer
nreusch  (posted 2018-11-15 07:20:09.0)
This is a response from Nicola at Thorlabs. Thank you for your inquiry. I am very sorry about the fact that we cannot specify coherence features for the CPS modules. Unfortunately, we do not have data about the spatial coherence length or area for these modules. The temporal coherence length, however, is related to the spectral emission bandwidth. A typical spectrum for each module is shown in the spec sheet. Please note that these plots are typical only and will vary from unit to unit. In some cases, the resolution of the spectrometer/OSA is not sufficient to show the actual linewidth. Furthermore, the temperature of the CPS modules is not actively controlled and for some modules, you will see that temperature also affects mode distribution.

This is a response from Nicola at Thorlabs. Thank you for your inquiry. A list of suitable light sources for our red-sensitive as well as our green-sensitive holography plates is shown at https://www.thorlabs.de/newgrouppage9.cfm?objectgroup_ID=6716&tabname=Other%20Components. We also recommend diverging the light of a collimated source by means of a lens. If you would like us to recommend a diode for your specific application, please do not hesitate to contact us with further information about your setup.

Hi! We are using several different CPS modules in a custom built mount that happens to electrically connect the aluminum housings. We learned that typically the housings are electrically isolated from +/- leads. However, sometimes it's not the case, to a point when a module would turn on undesirably by receiving power from am adjacent module via the connected housings. I could not find any info on the housing wiring/isolation vs +/- leads. If the parameter is not rated, is it in principle model-specific of sample-dependent? Thanks!
swick  (posted 2018-08-09 03:56:32.0)
This is a response from Sebastian at Thorlabs. Thank you for the inquiry. The CPS modules are not isolated. We recommend to use floating supplies or the modules need to be mounted in an isolated way. I contacted you directly for assistance.

Hello, I'm interested in the CPS 635R. Are there any internal electronics that would limit the input voltage bandwith? Would this diode be suitable for modulation in the 100 kHz - 1MHz range?
YLohia  (posted 2018-05-09 01:45:41.0)
Hello, thank you for contacting Thorlabs. The CPS line of diodes can only be used in a constant power mode, which prevents any modulation capability.
biegel  (posted 2018-01-15 14:16:06.253)
I have a cps532 laser. I am driving it with an LDS5. The output light intensity wanders over 50% with occasional jumps in power and occasional high frequency noise. The description mentions internal photodiode feedback control. How does that work internally? Perhaps that is defective?
YLohia  (posted 2018-03-02 09:41:49.0)
Hello, thank you for leaving feedback regarding CPS532 and my apologies for the problems you are encountering with your unit. The photodiode is not built-in, since this is a frequency-doubled module and the pump diode is 1064nm (there is a filter to attenuate this wavelength before it hits the photodiode). It is quite likely that this problem is caused due to a thermal issue as the diode and crystal continue to warm the output power cycles, or perhaps the temperature of one of the components is cycling. These 532nm units tend to be particularly sensitive to temperature due to the non-linear crystal inside. Providing some heatsinking could fix the issue. Sometimes issues like this can also be caused by power supplies that are not outputting a constant 5V. I have reached out to you directly via email to troubleshoot this further.

Hello, I am interested in the CP980S. Could you state an approximate value for the beam quality factor or alternatively the typical beam divergence (the data sheet states a max. divergence of 1.5 mrad) and the position of the waist?
nbayconich  (posted 2018-01-15 05:09:40.0)
Thank you for contacting Thorlabs. At the moment we have not measured the M^2 quality factor for these CPS laser diodes. The M^2 factor will be similar to our other fabry perot laser diodes. For improved beam quality, a spatial filter could be used, but that would reduce the total power.

tfrisch  (posted 2017-12-15 08:34:01.0)
Hello, thank you for contacting Thorlabs. The internal laser diodes are typically TE polarized. However, as the housing of the tube is cylindrical, you may rotate the entire unit such that the polarization is either vertical, horizontal, or any arbitrary linear state.

I noticed that the collimated beam profiles of your laser modules are very nice and homogeneous. Do you sell the collimation lenses in these modules as separate products or would you be able to sell them to us independently of the laser modules ? The reason I'm asking this is because I have difficulties getting homogenous collimated beams using the standard Thorlabs molded aspheres because they produce lots of ring-like features in the collimated beam. I also have a CNC polished asphere from Thorlabs here which seems to show the same ring-like intensity modulation. My light source is a superluminescent diode at 840nm with beam divergence angles of 10 and 30 degrees.

Response from Jeremy at Thorlabs: Unfortunately the coherence length is not something that we spec at the moment. As an estimate, it should be more than 200mm based on some initial measurements. We will post the results on this feedback page once we have measured this.

Response from Jeremy at Thorlabs: The CPS196 is a class 3R so you would definitely need to use laser safety glasses with this. One possible candidate for this wavelength is the LG4 (http://www.thorlabs.com/newgrouppage9.cfm?objectgroup_id=762&pn=LG4).

How long is the coherence length of the laser diode CPS180?
guoqiang.xia  (posted 2012-11-08 04:43:49.59)
From your SPEC sheets, it is shown that the working temperature of CPS180 is from -10 to 50 °C, CPS182 is from -10 to 60 °C, while for CPS196 it is from -10 to 40 °C, could you please let us know what is the reason for such differences? They are all 635nm lasers. What will be the life time for CPS180 if its surrounding temperature is 40 °C? Whil its life time drop significantly? Thanks!

Response from Tim at Thorlabs: You are correct that the photodiode is not directly connected to the outside world. The CPS modules have two wires for the power supply. This feeds an internal integrated driver, which is what actually controls the power using the internal photodiode for feedback.
user  (posted 2012-06-29 01:30:00.0)
Could you please calrify the statement "The driver in the CPS module uses an internal photodiode of the laser diode for feedback in a power control loop, which enables power stability within 1%."? Because from the web photo of cps196, I only found two wires at the back end of the laser, which must be power supply, so the internal photodiode is not connected to the outside world, how can there be a feedback? I am puzzled, please help here. Thanks

Response from Javier at Thorlabs to dfwenge: Thank you very much for contacting us with your inquiry. Regarding question (1), we actually had not considered adding a strain relief assembly to these laser diode modules before. I will discuss your suggestion with our electronics design engineers and get back to you. Also, you can certainly solder the the leads back onto the circuit board; I would not expect any damage to the laser diode from doing this. (2) We do offer pinholes; however, the maximum size that we stock is 150 um. Nonetheless, we can offer a 250 um diameter pinhole that you could adapt to the front of the CPS182 as a non-standard item. I will contact you directly for further discussion.

dfwenge  (posted 2011-06-06 11:28:14.0)
I have 2 comments: 1. After using a CPS182 laser module in a experiment where the laser is often moved to various postions the power leads have broken off the connectors. I have strained relieved the power cables on a spare unit using shrink tube. This seems to work okay but it takes up more space than I would like. Have you considered providing a strain relief design on the units you sell? If I try to solder the leads back on the connector, is there a potential to damage the laser diode by overheating? 2. Do you sell a pinhole, say around 250 microns in diameter, that would mount on the front output plate of the CPS182. Regards, Dave Wenger, SNL 505-845-7206

Response from Javier at Thorlabs to jhelt275: Thank you very much for contacting us. All the CPS modules are operated in constant power mode, which means that the power is regulated using the feedback signal from the laser diode's internal photodiode.

Response from Javier at Thorlabs to jmansell: The output of the CPS196 is polarized. The polarization is parallel to the fast axis of the laser diode, which is defined as the long, rapidly divergent axis in the output beam cross section. The slow axis corresponds to the low divergence axis of the laser diode output.

Laurie  (posted 2009-04-15 15:36:55.0)
Additional Response from Laurie at Thorlabs to Aidi: Upon speaking to a colleague here, I would like to add to my previous post. The main issue you will have is noise. Due to mode hopping as the diode temperature changes or as the diode ages, there will be times that the laser is hopping between two longitudinal cavity modes. Additional noise sources could come from the servo loop. These products are designed as alignment tools and not as low noise optical sources. For low noise performance, a constant current drive with a temperature-controlled mount is recommended. The user then needs to find a stable operating point in both current and temperature. Also the user should know that this stable operating point may change with time. We hope this additional information is helpful.
Laurie  (posted 2009-04-15 14:58:34.0)
Response from Laurie at Thorlabs to aidi: We do not have concise data for the power stability of our CPS modules compared to one with a TEC controller. The laser diodes in our CPS laser modules are operated in constant power mode, which makes them very stable in terms of optical power. However, since there is no temperature control for these diodes, heat can build up in the junction causing instability. Although this instability will be small for low powers, a TEC-controlled environment will definitely lead to more stability.
aidi  (posted 2009-04-15 05:09:54.0)
How good its optical power stability compared to the one used TEC controller? Thank you

Response from Laurie at Thorlabs to g.gray: Thank you for your comments and feedback. We greatly appreciate hearing from our customers concerning possible extensions to our product lines. Currently, we are in the process of expanding our laser diode module offerings, but none of the items in the pipeline are for the wavelengths you suggest. Thorlabs has an internal forum where product ideas can be posted. I will be sure to add your suggestion to that list in the hopes that it will be adopted. As an alternative, you might consider our unmounted laser diodes, which are offered at both of these wavelengths and can be found on our website at this link: http://www.thorlabs.com/NewGroupPage11.cfm?ObjectGroup_ID=7 Thorlabs also offers aspheric lenses for collimation and laser diode mounts if you decide to pursue this avenue.

Laser Module Mounting Adapters


Mounting Adjustable Focus CPS Laser Diode Modules

These adapters are available for those wishing to mount the laser module housing into SM1 (1.035"-40) lens tubes, 30 mm cage systemsØ1/2" posts, or Ø1/2" or Ø1" mounts. Please see the application photos in the Overview tab for more details. The AD8F and AD11F are also offered as part of a series of mounting kits; see below for details.

The KAD8F, KAD8NT, KAD11F, and KAD11NT Adapters provide ±6° of pitch and yaw adjustment. Two 80 TPI fine adjustment screws on the front plate of the adapter control the pitch and yaw position and can be turned using a 5/64" (2.0 mm) hex key.

Please note that the knurled knob used for focus adjustment on the CPS635F, CPS650F, and CPS670F laser modules is too large for the mounting adapter bore. This knob can be unthreaded to mount the module in the same manner as the collimated versions, as shown in the animation to the right. Please make sure to loosen the setscrews locking the knob in place before unthreading; not doing so can damage the threading. Alternatively, the module can be mounted by threading the cord and phono plug through the adapter first.

5 VDC External Battery Pack

  • Portable USB Battery Pack with 5 VDC Output
  • Compatible with CPS Laser Modules
  • 10 000 mAh Capacity

Thorlabs offers the CPS1 Battery Pack for powering our CPS laser modules and other USB-powered devices. The CPS1 battery pack outputs 5 V and offers 10 000 mAh capacity. A fully charged CPS1 battery pack can power any CPS laser module for at least 36 hours of continuous operation. The pack includes a USB-to-Micro-USB cable for charging and a custom USB-to-Phono cable for powering the CPS laser module. To activate the battery, simply push the power button once. The pack may be charged using standard 5 V USB chargers for portable devices or using a computer USB port. While the battery pack is charging, it can still supply power to an attached laser module.

The CPS1 Battery Pack also includes an LED flashlight adjacent to the micro-USB port. The flashlight is activated and deactivated by holding the power for two seconds.

When connecting the CPS Diode Module, the module and adapter should be connected first. Then the adapter cable should be plugged into the isolated power supply to avoid a short circuit in the phono jack. Please note that the USB adapter included with this battery pack is not intended to be used with power supplies that are not current-limited or isolated from ground, such as some computers or laptops.

Please note: Due to shipping restrictions for lithium ion cells, the CPS1 battery pack is not available for purchase in certain countries. In countries where it is available, the battery pack must be shipped separately using specifically regulated shipping methods and may require special shipping and handling charges. Our sales team is available to answer additional questions concerning the shipment of this battery pack.
