【 摘 要 】

Injection lasers were developed on the basis of the solid solution Pb1-xSnxSe for the spectral range of 16 μkm, where the rotational-vibrational absorption lines of heavy molecules are placed. For this purpose, were used, composition the solid solution Pb1-xSnxSe near the inversion point xi= 0.12. Single crystals Pb1-xSnxSe (Eg = 0.077 eV) were grown by directional crystallization from the vapor phase.
