Abstract
The present invention relates to a solid solution semiconductor laser element material which can form a laser element which oscillates in an infrared region of wavelength 0.2-8 .mu.m, varies wavelength and is operable in the vicinity of room temperature, particularly a laser element of a lattice-matching double hetero junction or lattice-matching quantum well structure. The disclosed solid state semiconductor is made of a material selected from a material having the general chemical formula
