Paper Abstract

Influence of the high-power laser radiation on the piezoelectric resonance in the nonlinear-optical KTiOPO4 crystal was observed. Equivalent crystal temperature can be directly determined from the piezoelectric resonance frequency during interaction of the laser radiation with crystals. Frequency kinetics of the different piezoelectric resonances of the KTiOPO4 crystal were observed for the different pump laser powers up to 20 W. The KTiOPO4 optical absorption coefficient and the amplitude of the crystal inhomogeneous temperature distribution were obtained from the kinetics data. A theoretical model of the piezoelectric resonances on the basis of the Rayleigh-Ritz method is proposed.
