Paper Abstract

The spectra of the optically pumped ZnMgSSe/ZnSe multiple quantum well separate confinement heterostructure lasers and the PL spectra of the heterostructures were investigated as functions of temperature (T=80-500 K), excitation intensity (Iexc=0.001-1000 kW/cm2) and number of excitation pulses (N=106). The laser threshold temperature dependence was investigated and explained by alternation of the spontaneous emission efficiency and spectral broadening with temperature rise. It was shown that at room temperature the active region overheating value does not exceed 10 K at high Iexc. It was established that the degradation of the heterostructures under high levels of excitation is due to the inherent laser emission interaction with the heterostructure leading to the appearance of intrinsic defects and to the inherent light stimulated interdiffusion at ZnMgSSe/ZnSe interfaces.
