2 . we design a configuration of frequency - doubler according to the optimum focus condition and the cavity stability condition | a + d | < 2 and optimize it based on " mode - matching " and " optimum coupling " . 99 . 96 % of optical impedance - match efficiency and over 95 % of spatial mode - matching efficiency are achieved eventually by using t = 10 % of input coupler in our experiment
( 2 )根据最佳聚焦条件和腔的稳定性条件( | a + d | 2 )对四镜环型倍频腔进行了设计，并分别从“模式匹配”和“最佳输入耦合镜透射率的选择”两方面着手对腔进行优化，在我们的实验中采用10的输入耦合镜，获得阻抗匹配效率为99 . 96 ，空间模式匹配效率高于95以上的模式。
