4.0um High-Power Benchtop Mid-Infrared FP-QCL Quantum Cascade Laser MIR-QCL-W4000 (Benchtop Light Source)

The 4.0um high-power desktop FP-QCL quantum cascade laser is developed by Idealphotonics as a continuous-wave laser with relatively high output power. It provides several hundred milliwatts of collimated output power, making it suitable for mid-infrared testing light source requirements. Additionally, the desktop FP-QCL laser module integrates a drive and temperature control module, and it can also be controlled via software to adjust the temperature and operating current of the laser. This ensures stable operation of the laser, maintaining the accuracy of the measurement results

Product features：Low power consumption, high power、 High side-mode suppression ratio、 Software intelligent control、 Compact structure and size

Application area：Mid-infrared testing light source、 Mid-infrared device analysis、 Mid-infrared system light source
