A new material based solid solution of chalcogenide materials that have Photoinduced effects: second harmonic generation, dvohfotonnoyu absorption, p'yezooptykoyu, PHOTOINDUCED transparency. The first time the substantial dependence of the band structure of the wavelength, geometry and capacity of coherent laser radiation. Based on the calculations of the band structure determined anisotropy of the effective mass of holes and electrons, respectively, in the valence band and the conduction band. The research opens new possibilities for use once synthesized chalcogenide material in devices with various changes lazernokerovanym appropriate optical constants. It used to be that every grown crystal has a fixed optical parameters that do not change or little change in service. Our research shows the ability to change these settings to a certain level without the need for synthesis of new crystals. The resulting material can be used for modulators and detectors of laser light in a wide spectral range from the visible to the infrared. Compared with other infrared materials, such as binary and ternary sulphides, it is possible to control parameters using an external light. They also have large limit values for laser density - up to 1 GW / cm2. A new direction using crystals studied is the potential creation based on these memory elements. This one is a bit of information using an external laser with enough power that changes the corresponding optical functions primarily absorption and refractive index, a reading information held continuous lasers of low power
