Abstract: In this paper,by analysing the characteristics of thermal heat absorption of active medium in high power solid state laser,we present the nonradiactive relaxation model of excited ions in active medium in continuous operation and give the dependence of thermal heat absorption caused by nonradiactive relaxation on laser oscillation.The influence of laser oscillation on diopters of laser rod is also given.Experimental results show accordance with theoretical model analysis.
