InAs/AlSb quantum cascade lasers emitting at 3.06 and 3.22μm at room temperature has been studied. The lasers with high reflection coating on back facets operated in pulse mode up to 400 and 423 K, respectively. The obtained results showedno dramatic performance degradation of the InAs-based QCLs with decreasing emission wave length down to 3μm
