- Abstract
Diffusion injection lasers based on PbSnSe alloy, emitting in a wide spectral range of 10-46.5 μm depending on the composition and temperatures are fabricated. A technology for growing high-quality single crystals from the vapor phase under conditions of free growth is developed. The dependences of the total emission intensity on the pump current and the emission spectra of injection lasers based on PbSnSe are studied. In these samples, lasing of long-wavelength radiation to a record wavelength of 46.5 μm is achieved.
