CW quantum cascade laser

L12005-1900H-E

DFB-CW drive type quantum cascade laser with lens

 

It is a DFB-CW drive type quantum cascade laser (QCL) with a collimation lens built into the airtight package (HHL package).
Lens alignment of invisible mid-infrared laser light is no longer required, and ease of use has been improved. By controlling the temperature with the built-in TE-cooler in the HHL package, it is possible to sweep the emission wavelength without mode hopping while maintaining the single mode operation.
