Abstract
For more than fifty years numerous experimental and theoretical works give evidence of the crucial functional role of the nonlinear-optical crystal heating in various processes of laser frequency conversion including second harmonic generation. However to the present day no precise methods have been proposed for the determination of the true crystal temperature in processes of nonlinear-optical frequency conversion [1]. To our belief the notion of the “Equivalent temperature of the non-uniformly heated nonlinear-optical crystal” that was recently introduced in laser physics [2] can help in solving such problems.
