摘要

采用光谱物理公司生产的、平均输出功率为1.1W、脉宽为90fs的再生锁模掺钛蓝宝石(Ti:Sapphire)激光器作为泵浦源,KTP作为非线性光学介质,以及BBO作为腔内倍频晶体,制成了一台同步泵浦腔内倍频飞秒KTP光学参量振荡器。其输出调谐范围为528nm至586 nm,最佳平均输出功率为240 mW左右,脉宽约为100 fs。在无反馈伺服系统的情况下,该参量振荡器可维持振荡达三个小时。

Abstract

Using the Spectra Physics Company produced 1. 1 W, 90 fs regenerated mode locked Ti:Sapphire laser as pump source, KTP as nonlinear gain medium, and BBO as a intracavity frequency doubling crystal, we construct a synchronously pumped intracavity frequency doubled fs KTP optical parametric oscillator (OPO). It's output tuning range is from 528 nm to 586 nm, the optimal average output power is 240 mW, and the pulse width is about 100 fs. The oscillation of this OPO system can last for about three hour, even without a feedback system.
