The LDM Series of compact laser sources are well suited to benchtop optical experiments. They are available at six wavelengths: 405 nm, 635 nm, 670 nm, 785 nm, 850 nm, and 1550 nm.

The Ø1.40" by 5.8" housing contains a Fabry-Perot laser diode with a bandwidth typically around 1 nm, collimating lens, and power controller. Each laser diode module includes a built-in shutter and internal SM1 (1.035"-40) threads for mounting with an extensive range of optomechanical devices from lens tubes to lens mounts. These laser modules are typically used as alignment aids within an SM1 Lens Tube system, as shown in the figure below to the left.

The LDM modules can be mounted to any optical table using one of our C1512(/M), C1513(/M), KM200V(/M), or VC3C(/M) V-groove mounts. Besides the mechanical shutter, the module also features a remote interlock connection and key-lock power switch. The laser module has an enable/disable toggle switch, laser on indicator LED, and top-located power adjustment pot controller.

The power can be adjusted from 0 to full power by adjusting a pot, as shown in the image at the bottom right. The output of each laser diode is polarized and multi-longitudinal mode. When the Laser Enable button is facing up, the light will be vertically polarized, with the exception of the LDM635, which will have horizontal polarization. Each LDM comes with a universal power supply.

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

Safe Practices and Light Safety Accessories

  • Laser safety eyewear must be worn whenever working with Class 3 or 4 lasers.
  • Regardless of laser class, Thorlabs recommends the use of laser safety eyewear whenever working with laser beams with non-negligible powers, 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.
  • Laser Safety Curtains and Laser Safety Fabric shield other parts of the lab from high energy lasers.
  • 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 Class 3R lasers produce visible and invisible light that is hazardous under direct and specular-reflection viewing conditions. Eye injuries may occur if you directly view the beam, especially when using optical instruments. 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 in this class are limited to 5 mW of output power.  Class 3R
3B Class 3B lasers are hazardous to the eye if exposed directly. Diffuse reflections are usually not harmful, but may be when using higher-power Class 3B lasers. Safe handling of devices in this class includes wearing protective eyewear where direct viewing of the laser beam may occur. Lasers of this class must be equipped with a key switch and a safety interlock; moreover, laser safety signs should be used, such that the laser cannot be used without the safety light turning on. Laser products with power output near the upper range of Class 3B may also cause skin burns.  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

How would one mount a LDM405 laser inside a cage system directly? Is it possible with off-the-shelf parts from Thorlabs, or do we have to custom machine some parts?
ksosnowski  (posted 2024-02-09 12:04:19.0)
Thanks for reaching out to Thorlabs. LDM405 and the LDMxxx series of laser modules have internal SM1 threading at the output aperture which is 0.15 inches deep. Using an externally threaded lens tube coupler like SM1T2, which is 0.5 inches long, you can connect the laser to the SM1 threads in the cageplate CP33 which are 0.35" deep. The outer diameter of the LDM405 is 1.40 inches as shown on our 2D CAD file. We do not have any adapters for this specific size to raise the diameter to 2 inches for use in the larger 60mm cageplate like LCP34. There are other adapters to step between 30mm to 60mm cage sizes if needed however.

Hi! In my lab we bought a LDM785 laser and the laser spot is pretty ugly, resembles an interference pattern and I couldn't clean it even with a monomodal fiber, because I get a circular interference pattern no matters what fiber I use. I would like to know if you have some suggestions to improve the spot. Thannk you.
ksosnowski  (posted 2023-02-09 11:56:18.0)
Hello Ana, thanks for reaching out to Thorlabs. It sounds like the fiber is not behaving as single mode in this setup. This could be due to the choice of fiber or launch conditions. I have reached out directly to discuss your application further.

Thanks for reaching out to Thorlabs. While we currently do not have any compact modules like LDM1550 for 1064nm or 1319nm, depending on your spectral and power requirements you may consider our Benchtop Fiber-coupled Lasers for turnkey operation. For more narrow spectra it may require a diode and driver. I have reached out directly to discuss your application further.

What is the light output stability of these lasers in percent? Would like to see 523nm and 940nm versions of these lasers! What is the beam divergence?
YLohia  (posted 2019-01-02 09:15:21.0)
Hello, thank you for contacting Thorlabs. We specify the stability in dB in the spec sheets of these lasers, with short term stability being 0.01 dB (0.230%) and long term being 0.1 dB (2.329%). Currently, these lasers are collimated by checking to make sure that the beam size stays the same over a distance of about 3m. We realize this is not a very exact process and are looking to change it in the future, but for now this is the procedure so we do not have a definitive spec for divergence. Over 3m, it's typical to see around 0.08 - 0.60 mrad divergence. I have posted a suggestion for these two wavelengths on our internal engineering forum for further consideration.

I'm interested in the degree of polarization of these laser diodes. Apart from the shutter & interlock, what are the main differences to the lower-priced CPS family of laser diode modules?
nbayconich  (posted 2017-10-19 10:51:58.0)
Thank you for contacting Thorlabs. The LDM series laser diodes typically have a TE linear polarization, and have a typical PER of 20-30 dB. The LDM series have an adjustable output power and are offered with a higher output power and a longer available wavelength range than the CPS diodes. The CPS laser diodes are more for a simple plug and play option and do not have the ability to adjust the output.

This series has an 'enable' button. There needs to be provision to enable *remotely*; sometimes it is not accessible, and its also not good for alignment. The lack of one is a big problem for us right now. Obviously it would invalidate warranties etc, but would it be practical to open it up (the screws at the back presumably) & add a parallel connection across the push button to provide remote enable? (Holding it down doesnt work :-( )
jlow  (posted 2014-07-29 04:05:31.0)
Response from Jeremy at Thorlabs: Thank you for your feedback. We will look into the possibility of adding this in the future. With regard to modification, it is possible to do something like that but that will definitely void the warranty. I will contact you to provide some detail on the switch.

Polarization state of the LDM405 laser module: the output appears to be polarized with the E-FIELD VERTICAL when the output enable button is facing up. I confirmed this by using reflection from a glass plate to observe the Brewster angle as well as by passing the beam through your LPVISE 100-A linear polarizer, which passes the beam when its polarization mark (red dot) is aligned VERTICALLY when the LDM405 is mounted with its controls facing up.

cdaly  (posted 2014-03-25 12:26:29.0)
Response from Chris at Thorlabs: There isn't a specific part dedicated for this purpose, but you could use an SM1T2 lens tube coupler with a CP08FP fiber port mounting cage plate in order to mate the two together. Both the LDM laser modules and this plate have internal SM1 threading which would thread onto the externally SM1-threaded coupler.

Response from Phong at Thorlabs: We do not test the LDM1550's M2 parameter since it is not optimized for this. If you're looking to achieve a good M2 value, we would suggest coupling the laser's output to a single mode fiber to clean up the profile to make it more Gaussian.

Response from Buki at Thorlabs: Thank you for your feedback. Unfortunately the only way to implement a remote enable function is just how you described, by running a pair of wires in parallel with the internal tact switch. If you prefer that we do it, please contact to request a quote. Please note that the enable circuit requires a momentary closure to enable and disable the laser. You can leave the switch closed as long as you wish, but you need to return it to an open state and then close it again in order to toggle the state of the unit.

Hello, I purchased one of your LDM635 and LDM405 laser modules, and I need to mount it inside an enclosure and control it remotely. I understand from a previous post that they have already tried using the "Interlock" connection, but even with that switch contact closed, the "enable" button must still be pressed manually to turn the laser on. Is there anyway that this laser can be controlled remotely or without using this toggle switch? Like the user before mentioned, I might have to resort to disassemble the laser and bring the "enable" switch contacts out on a pair of wires to a second control relay. This I would prefer not doing in case of damaging the laser components. Martin

In my opinion, the most important feature of this type of laser module (LDM635, etc.) is the fact that it has 1" diameter lenstube thread on the end. I would never have known this if I had not gone into the "drawings" and looked for it specifically. This feature will sell this laser to anyone who uses Thor lenstubes and yet it is not promoted on the front page. You are missing out on sales by not pushing the lenstube feature of this alignment laser. Everyone who uses lenstubes will have a use for an alignment beam (battery driven!) that simply screws onto existing fixtures. Wake up!
