Abstract

Quantum cascade (QC) lasers are a new type of semiconductor laser for the mid-infrared based on electronic intersubband transitions. For gas spectroscopy, the lasers have to operate with stable single-mode emission and controlled tunability. This article describes the first cw QC-distributed feedback (DFB) lasers operating in both atmospheric windows as well as dramatic performance improvements in pulsed QC-DFB lasers using an index-coupled grating.
