Features

  • Combined Current and TEC Controllers
  • Maximum Laser Currents of 200 mA, 1 A, or 3 A
  • Constant Current (CC) and Constant Power (CP) Modes
  • Full PID Feedback Loop with Independent P, I, and D Settings
  • Extensive Protection Against Laser Diode Damage
  • Supports Many Standard Pin Configurations for Easy Integration into Systems

These 100 mm x 160 mm board-level controllers combine a low-noise, low-drift current source with a precise TEC controller. Designed for easy integration into OEM applications, these euro-sized boards are ideal for products or systems where excellent laser emission stability is required. The analog interfaces offer easy access to parameter settings and readout.

These laser diode controllers support constant current (CC) and constant power (CP) modes, as well as all laser and monitor diode polarities (CG/AG). The connected laser interfaces with the controller through a 15-pin D-Sub connector. A fixed-ground-level design significantly improves noise, transient suppression, and output stability. The laser operating current can be modulated by an external control signal.

The built-in temperature controller includes a full PID feedback loop with independent P, I, and D settings, which can be individually optimized. A wide variety of temperature sensors (such as thermistors and the AD335 Temperature Transducer) are supported. A standard 64-pin PCB connector provides access to output signals, analog control inputs, power supply connections, temperature sensors and thermoelectric cooler elements.

Accessories
We offer a display board (ITC100D) and front panel (ITC100F) for viewing and setting the system control parameters. In addition, we manufacture a 9-pin and 15-pin Y-cable (CAB430) for connecting the controller to our family of laser diode mounts with built-in TECs.

For further information, please contact Technical Support.

Hi, this is Nan with Calient. We bought the following parts for laser diode control: Part numbers are: ITC102 ITC100D ITC100F CAB430 But there is no user manual or how can we adjust laser diode current or power. Where can we have user manual? Thanks Nan

Hello, I was wondering how to remove the large knob on ITC100D when I want to install ITC100F to the ITC100D. I have tried several methods, but all failed, the knob looks fixed on ITC100D very well. Thank you. Li

This is a response from Stefan at Thorlabs, Thank you very much for your feedback. The head of the control knob with the black line is a cap which is just plugged in. By removing this cap you have access to a screw which fixes the knob to the board. I will contact you directly to check if there are any further questions.

How to measure temperature at celcius degree. i use ITC 102 and ITC 100D for DFB laser 0-70C

This is a response from Stefan at Thorlabs. Thank you very much for your inquiry. There are several ways to get the actual temperature with the ITC102 displayed. In the manual on page 6 http://www.thorlabs.de/thorcat/7100/ITC102-Manual.pdf you can find the TEC specifications and temperature sensors control range. With the ITC100D display panel connected you can display the “Set” and “Actual” temperature on the display. Please check that the Jumpers are set as described in the manual from page 45-46: For the ITC102 both jumpers ILD and ILim have to be at position 1. With the knob you can display from counter- clockwise to clockwise following parameters: Photo diode current IPD Laser diode current ILD Laser diode limit current ILIM Set temperature1) (or resistance2)) value TSET Actual temperature1) (or resistance2)) value TACT TEC limit current ITLIM For higher display accuracy you should re-calibrate the ITC100D from time to time. For adjusting Tact bring your temperature sensor to a well-defined temperature and adjust the ITC100D reading to that temperature using potentiometer P5. P5 is the second potentiometer from the right below the turning knob, please see also the picture in the manual on page 45. Alternatively you can also read out the temperature from the 64 pin connector directly at Pin C10 (see manual page 19 for the pin diagram). The actual temperature (TACT ) can be calculated with the conversion factor 50mV/°C from the voltage drop (-1 ... +4 V ) along a load resistance, we recommend to use at least 500kOhm load. I will contact you directly to check if you have any further questions.

I'm trying to figure out how to play with the TEC mode of ITC100. When I change the Tset to a certain value (I changed it to 40C when Tact was at 26.1C), the Tact seems to change super slowly. Is this normal? Reading through the manual (the polarity part in the TEC section), it seems like the Tact reaching the Tset seems pretty fast, so that we can check the polarity of the system. Also, it seems like Tact is increasing when LD is on, and is decreasing when LD is off. I am having trouble with the temperature control. Any help?

A response from Julien at Thorlabs: Thank you for your feedback! Based on the description of the problem, it seems that the settings of the temperature feedback loop might be the issue. the user can set the PID as well as the maximal TEC current so as to adapt the TEC driver to the system considered. I will contact you directly to discuss the exact details of your set up.

Hello, Is there any plan to extend the OEM ITC controllers to higher current ranges? It would be very helpful to be able to drive TA chips with them, and many require up to 4.5A

This is a response from Thomas at Thorlabs. Thank you very much for your inquiry. There are no plans to extend the current ranges of these controllers. We could offer you a special item which can provide a higher current. I will contact you directly with more detailed information.

Hello, We want to use the ITC133 in a portable application and our power supply comes from a 24VDC battery pack. Do we need to convert the voltage into +/-12VDC ou simply +12VDC? Is there a power supply that you can reccomend us to use the ITC133 from a 24VDC battery? Thank you very much. Best Regards, S. AVILA.

Response from Jeremy at Thorlabs: While the ITC133 can be used to drive the L915P1WJ, you will still need other devices such as a TEC mount, adequate heat sink (and maybe a fan to cool the fins of your heat sink as well). You would also need a power supply that can provide the adequate current (please see page 11 of the manual for the specifications).

Hi I'm a university student from South Korea and have an enquiry about ITC133 In my bio-optics laboratory, I've got some high-power laser diodes such as L915P1WJ and others pin code A or D. Can I drive them with ITC133 safely without any other devices?

Response from Laurie at Thorlabs to hase: Thank you for your inquiry for our OEM diode and temperature controllers. We do have several customers that use this instrumentation for telecom fiber testing applications, as well as a leading manufacturer of subsystems that implements these. Unfortunately, we do not have any specific data for the mean time between failures of these items. If you can provide us with your requirements, we will discuss your application with our engineers to see if we can ensure that this item will meet your needs.

Could you give me the reliability data of ITC102 and PDB140C, such as MTBF? I am considering if they can be integrated into a system for telecom fiber testing application.

Front and Display for OEM Laser Diode & Temperature Controllers

The ITC100D is a separate display board that can be connected to the ITC100 Series controllers to set the system control parameters. To make the controllers more user friendly, we offer the ITC100F, which is a front panel for the ITC100 Series controllers that covers the control and display boards .

Please note that before installation of the ITC100F can begin, the large analog output control knob must be removed from the ITC100D. To remove the knob, pry off the top surface of the knob with the black indicator line. This will uncover a screw that fixes the knob to the panel. Once the ITC100F is installed, the analog control knob can be placed back into the system allowing for normal operation to continue.
