Aquantum cascade laser contains active regions and conducting regions in turn. An active region contains three electron subbands. An electron injected into the upper subband undergoes a stimulated transition to the lower subband and reaches, after a nonradiative relaxation process, the lowest subband.

In this chapter, we present a brief overview of the QCL technology with an emphasis on the commercially important 3 μm to 12 μm spectral region covering the infrared fingerprint spectral region and the two infrared atmospheric windows (3 to 5 μm and 8 to 12 μm).
