Stimulated emission from optically excited CdxHg1−xTe structures at room temperature
2012
Abstract Main requirements for the optimization of Cd x Hg 1− x Te (MCT) structures with a view to increasing the wavelength of stimulated emission under optical pumping are discussed. A 2–2.5 μm stimulated emission from optimized MCT structures is observed experimentally at room temperature. The measured values of the gain in the active medium amount to 50 cm −1 at a 2 μm emission wavelength.
