Abstract

A model of nonlinear-optical crystal heating is proposed that enables one to determine temperature distribution inside the sample under action of laser radiation from the measurements of internal crystal temperature. Absorption and heat transfer coefficient at crystal-air boundary are also determined. Crystal temperature is measured by analyzing changes of piezoelectric resonance frequencies of the sample.
