摘　　要：由准三能级系统的速率方程,计算当激光谐振腔处于稳态时的反转粒子密度数,从而建立腔内基模振荡所满足的稳态方程.在阀值附近,计算出泵浦速率Rth,即可解出相应的阀值功率Pth,最后通过对三波耦和方程的倍频分析计算倍频效率.This paper tells about how to calculate the inverted population density by using the rate equation of quasi three-level system when the Laser resonant cavity is in a steady state,and to set up the steady-state equation which satisfies the in-tracavity foundamental mode's oscillating.From the close valve value,the pumping rate (Rth),and the corresponding valve value rate (Pth) can be obtained.At last,the frequency multiplier efficiency can be calculated through analysing the theory of intracavity frequency multiplier.
