DFB-CW QCLs with built-in lens

The lens-integrated package for DFB-CW QCLs provides a collimated beam in a sealed housing. TEC (peltier) and thermistor for temperature stabilization of the QCL-laser chip are inside the housing. This package allows direct access to a usable, collimated beam while eliminating the hassles involved with aligning and collimating an invisible mid-IR laser.
