ITC4005QCL In Stock

The ITC4005QCL by Thorlabs is a state-of-the-art laser diode current and temperature controller designed to support a wide variety of Quantum Cascade Lasers (QCLs) with its high compliance voltage of 20 V. This combined laser current and TEC controller brings together the functionality of an LDC4000 series current controller and a TED4015 temperature controller into one compact unit. The ITC4005QCL delivers precise and stable currents, with a maximum operating current of ≤5 A. It offers outstanding temperature stabilization to within 0.002 °C over a period of 24 hours.

The ITC4005QCL is a versatile product, capable of connecting laser diode and monitor diode pin configurations, as well as two-tab C-mount QCL and ICL packages. This makes it an ideal solution for a wide range of applications. It can be used with most common temperature sensors, and its digital PID controller allows for adaptation to different thermal loads. Automated tuning of PID can be done with the built-in feature or by adjusting each parameter independently.

The ITC4005QCL from Thorlabs offers an easy-to-use control system through its large, clear LCD display and simple operation menus. It also includes front panel keys, making it even more convenient to use. Besides the front panel display, this device can be controlled using a SCPI-compatible USB Interface which offers a higher setting precision and measurement resolution than the conventional method. With multiple outputs and a digital I/O port, the ITC4005QCL connected to different sources with ease- including the built-in function generator that provides analog modulation of the laser output.

This Thorlabs controller boasts a number of advanced features, including Quasi-Continuous Wave (QCW) operation mode, easy auto-tune PID, and comprehensive laser and TEC element protection. The ITC4005QCL is designed to provide silent and energy-efficient operation, making it an ideal choice for the safe and reliable operation of medium to high-power QCLs, ICLs, and laser diodes in both laboratory and production environments.

The ITC4005QCL is capable of utilizing either Continuous Wave (CW) or Quasi-Continuous Wave (QCW) operation, and is also equipped to drive LEDs. With its active power management for efficient operation and excellent temperature stability, this controller is a top-of-the-line choice for a range of applications. The ITC4005QCL also features an adjustable temperature sensor offset, further enhancing its versatility and performance capabilities.
