4.43µm High-Power Desktop DFB-QCL Mid-Infrared Quantum Cascade Laser 100mW (TDLAS Integrated Control Module)

QCL5184DFB-5. 18um High-Power Desktop DFB-QCL Mid-Infrared Quantum Cascade Laser is a mid-infrared testing laser developed by Idealphotonics in the first half of 2019. The low-loss atmospheric window is beneficial for space optical communication testing research. Our desktop light source has high output power and does not require ITAR review, making it the preferred choice for commercial mid-infrared testing light sources. With a tunable range exceeding 100nm and an output power greater than 100mW, it meets the industrial testing needs of our customers. The laser features built-in ZnSe collimated output, ensuring stable output power with extremely high temperature and wavelength stability, surpassing the stability of traditional high-power quantum cascade lasers by several orders of magnitude.
