摘要
采用非临界相匹配方式，制成一台同步泵浦飞秒红外光参量振荡器。其输出波长的调谐是靠改变泵浦光掺钛蓝宝石激光器的输出波长而得以实现的，其调谐范围为１．０８～１．１３ｕｍ。在９０ｆｓ．１．１ｗ左右的掺钛蓝宝石激光器的泵浦下，同步泵浦光参量振荡器的输出功率为１００ｍｗ．而脉竟只有６０ｆｓ左右。
Using NCPM technique, we construct a synchronously Pumped fs infrared OPO.Tuning of the output wavelength of this OPO is realized via changing the Pumpingwavelength, and its tuning range is 1. 08￣ 1. 13 um. Under a pump power of 1. 1 W of a90 fs Ti: sapphire laser, the average output power of the synchronously pumped OPO is100 mW, and the pulse duration is about 60 fs.
