Abstract
Stimulated emission and optical gain in CdTe/CdMnTe graded index separate confinement quantum wells have been investigated as a function of optical excitation powers and temperatures. Maximum gain of about 100 cm-1 is obtained at 95K for a single quantum well under 2-3 kW/cm2 excitation. This value allows to design laser cavities compatible with the microgun pumped laser device concept. The temperature dependence of the gain still remains a problem (T0 = 110K).
