摘　　要：将复合腔调频技术应用于光参量振荡器。采用ＮｄＹＡＧ激光之三次谐波同步泵浦ＢＢＯ晶体，与传统的单独掠射光栅调频腔（Ｌｉｔｔｍａｎ结构）相比，在线宽相同前提下，降低了振荡阈值，提高了输出功率。同时给出了复合腔调频的物理机制。通过复合腔的特别设计得到了窄线宽。Tuning of a compound cavity has been applied to an optical parametric oscillator (OPO) for the first time to our knowledge, which not only reduced the laser threshold, but simultaneously realized narrow linewidth and high power output as compared with a tuning cavity using just the grazing incidence grating (Littman Configuration). The theoretical and experimental results are given as well as a practical experimental device as an example.
