| 摘 要： | 研究了光学参量振荡中的参量增益．对环形腔和驻波腔作了讨论．通过单块KTP晶体，利用Nd：YAP倍频稳频激光器产生的0.54μm的激光作为抽运源，并注入1.08μm的两个偏振光作为信号和闲置模，利用温度调谐和插入光楔的方法，在环形和驻波腔中实现了三波之间的强耦合作用．获得了高达110倍的参量增益，并测量了增益与抽运功率的关系．实验结果与理论分析基本一致

| Abstract: | The parametric gain of the ring and standing cavities was studied in this paper. By using the strong output of frequency doubled and stabilized Nd:YAP laser at 0．54μm as the pump source and the fundamental output at 1．08μm as the signal and idler modes, strong coupling of three modes in the ring or standing cavities is demonstrated. An optical wedge and a temperature controller are used to realize the three mode resonance simultaneously. Parametric gain as high as 110 is obtained. The relation between the gain and the pump power is also measured and the result fits to the theory on the whole. |
