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586nm，最佳平均输出功率为240mW左右，脉宽约为100fs。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。 A regeneratively mode-locked Ti: Sapphire laser with a mean output of 1.1 W and a pulse width of 90 fs as a pump source, KTP as a nonlinear optical medium, and BBO as an intracavity Frequency crystal, made a synchronous pump cavity multiplier femtosecond KTP optical parametric oscillator. The output tuning range of 528nm to 586nm, the best average output power of about 240mW, pulse width of about 100fs. In the absence of feedback servo system, the parametric oscillator can maintain oscillation for up to three hours.
