7.4um Low-Power Desktop DFB-QCL Mid-Infrared Quantum Cascade Laser 5mW (Desktop Light Source)

QCL7400 - 7.4um low-power benchtop DFB-QCL mid-infrared quantum cascade laser is a domestically advanced ultra-low-power QCL DFB laser developed by Idealphotonics in the first half of 2018. The tunable range exceeds 100nm, and the output power is greater than 20mw to meet the industrial needs of customers testing gas sensors. Our laser collimated output has stable output power and high temperature and wavelength stability, which is several orders of magnitude higher than the stability of traditional high-power quantum cascade lasers. It provides an excellent test light source for our mid-infrared test customers.

Product features：Low power consumption, high power、 High side mode suppression ratio、 Intelligent software control、 Small structure

Application area：TDLAS CO high-precision trace analysis、 Mid-infrared test light source
