Abstract
The influence of external irradiation of CO2, CO, Er:glass, Nd:YA lasers on the piezoelectric properties of the Ag2In(Ga)2Si(Ge)S(Se)6 crystals was investigated. The maximum photoinduced changes in the piezoelectric coefficient were observed after irradiation with CO2 laser. CO photoinducing bicolour beams with 5.5 μm wavelength cause at least 4 times smaller increase in piezoelectric coefficients. Therefore, it can be expected that the primary mechanisms cause the excitation of the phonon subsystem.
