摘要：

We have investigated the optical response of a red emitting CdTe/CdMgTe laser structure after optical excitation. For the first time, stimulated emission has been observed in this material system at room temperature, demonstrating the potential for the development of CdTe/CdMgTe laser structures in the visible spectral range. An analysis of our experimental data yields a threshold carrier density of about 3.5.10(12) cm-2 and a net gain coefficient of about 95 cm-1 at T = 300 K.
