BDN染料调Q激光器的效率

BDN染料调Q激光器的效率η是Q开关透过率T-0和输出窗反射率R的二元函数.我们用一个关于R,T-0的曲面可以表示此二次函数η=η(R,T0),该曲面形象地反映出η随R和T0的变化规律.正如所分析的那样,当R与T0数值相等时,效率η达到最大值.

Efficiency of the laser with BDN dye Q-switch

The efficiency η of the laser with BDN dye Q-switch is a function oftwo variables,T₀ and R.(Namely,T₀—transmittance of Q-switch,R—reflectance of output window).We can give the function of two variables η-η(R,T₀) represented by a curved surface above the R,T₀-plane.This gra-ph clearly shows how η varies with R and T₀,As shown,η will be in thevicinity of the peak value when R is approximately equal to T₀.
