The QCL provided covers the entire mid infrared and long wave infrared bands, and can be flexibly selected according to applications, such as high efficiency, medium high power output, or low power consumption. The application involves fields such as military, security, analysis, health, and environment.

The wavelength range is 3.8-12.5um, and most modules can output continuously at room temperature, and can provide corresponding DFB structures to achieve single-mode output or high-power output with large light-emitting surfaces.

In addition, corresponding laser drivers and temperature control devices can be provided:
