摘要: Nonradiative Auger recombination has limited room temperature continuous-wave (cw) operation of type-I interband lasers to wavelengths shorter than 3.36 μm. Using IV–VI semiconductor quantum well microdisk structures, near laser at longer is achieved. Their active region consists single wells PbSe embedded in PbSrSe barriers. Under optical excitation, mode cw emission 4.3 μm demonstrated up 2 °C. This proves the feasibility cw-operation long wavelength temperature.
