In present work spectral distribution of absorption coefficient in the range of 100 – 300 K was investigated and band gap values evaluated. Parameters of Urbach rule were calculated and linearity of temperature dependence of Urbach energy was showed. Thermo induced piezoelectric effect in a range of 297 ‑ 357 K was investigated. Laser induced kinetics of piezomodule was investigated and absence of irreversible changes was showed. Influence of heating the crystal during laser illuminating on piezoelectric module was adjusted.
