Dependence of the nonlinear-optical crystal piezoelectric resonance frequencies on temperature was exploited for detailed investigation of crystal interaction with laser radiation. Nonlinear temperature change of periodically poled lithium niobate (PPLN) crystal was observed in laser frequency doubling experiment. Optical absorption and heat transfer coefficients were measured for PPLN and lithium...
Conventional method for the precise determination of optical absorption coefficients of nonlinear-optical crystals is laser calorimetry [1]. It is based on measurements of the heating kinetics of air near crystal surface during and after laser irradiation. Both optical absorption α and heat transfer hT coefficients are then calculated by solving non-stationary heat conduction equation taking into...
