ABSTRACT:
Dependence of the periodically poled nonlinear-optical
lithium niobate (PPLN) crystal temperature on laser power in the course of
laser frequency conversion was measured using piezoelectric resonance.
Crystal’s temperature tuning
curves are precisely measured using concept of the
equivalent temperature. Both
optical absorption and heat transfer coefficients of the crystal are measured
employing kinetics of the crystal equivalent temperature.
