摘要
实验研究了非临界相位匹配 (NCPM)的内腔式KTP光学参量振荡器 (OPO)的光束发散角与OPO谐振腔参数的关系。证明了望远镜型共焦非稳谐振腔是压缩OPO光束发散角的有效方法。
The performance of the intracavity KTP OPO output beam divergence as a function of resonator parameters have been investigated experimentally. The Cassegrainian unstable resonator has been demonstrated to be one of efficient means to decrease the OPO beam divergence.
