7.42um Low Power benchtop DFB-QCL Mid-Infrared Quantum Cascade Laser 10mW (TDLAS Integrated Control Module)

QCL7420 - 7.42um low-power benchtop DFB-QCL mid-infrared quantum cascade laser is a 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 10mw 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.
