Thorlabs ITC4005 Combined Laser Diode and TEC Controller

Thorlabs' Combined Laser Diode and TEC Controllers combine the functionality of a LDC4000 series current controller and a TED4015 temperature controller in a single device. They are designed to provide precise, stable current for laser diodes with maximum operating currents from 1 to 20 A (see the table to the lower right for details) and excellent temperature stabilization to within 0.002 °C over a period of 24 hours. In addition to our standard versions which have a compliance voltage of 11 or 12 V, we offer two high-compliance-voltage drivers for our QCL and ICL lasers: the ITC4002QCL can provide up to 17 V at 2 A of current and the ITC4005QCL can provide up to 20 V at 5 A of current. For optimal noise performance, choose a controller that has maximum current and voltage ratings as close as possible to, but still higher than, the required voltage and current needed to operate your laser.

The controllers are compatible with all laser diode and monitor diode pin configurations and feature a constant current (CC) or constant power (CP) mode. Most common temperature sensors can be used, and the ITC4000 can be adapted to different thermal loads via a digital PID controller. It offers an auto-tune PID function or separate control of the P, I, and D parameters. For more details about these features please see the More Info tab. The controllers are also compatible with our line of laser mounts, some of which also include TEC elements.

The ITC4000 devices are controlled via front panel keys and intuitive operation menus on a large and easy-to-read graphic LCD display (see the Display tab for sample screens). Additionally, these controllers can be controlled by a SCPI-compatible USB Interface. A higher setting and measurement resolution is offered via USB operation since the front panel resolution is limited by the resolution of the display. Various outputs and a digital I/O port offer many control and connectivity options. The built-in function generator allows analog modulation of the laser output out of the box.

These controllers offer many advanced features such as Quasi-Continuous Wave (QCW) operation mode, easy auto-tune PID, and diverse laser diode and TEC element protection (see the More Info tab). The controller design also provides silent and power-efficient operation. These features make the ITC4000 Series an ideal choice for safe and secure operation of medium- to high-power laser diodes and LEDs either in the lab or in production environments. Thorlabs recommends recalibrating these controllers every 24 months and offers a factory recalibration service. To order this service, scroll to the bottom of the page and select Item # CAL-ITC4.
