We report both extracavity and intracavity simultaneous second-harmonic generation and compression of pulses at 1.25 mum from a synchronously pumped RbTiOAsO(4) -based optical parametric oscillator, using an aperiodically poled crystal of KTiOPO(4) . The 290-fs input pulses were temporally compressed to 120 fs, with average output powers as great as 120 mW. The experimental results are compared with a numerical model that uses data obtained by characterization of the input pulses by use of the frequency-resolved optical gating technique.
我们报道了使用非周期极化的磷酸钛氧钾晶体,在基于同步泵浦的RbTiOAsO₄光学参量振荡器中,实现了1.25μm脉冲的腔外和腔内同时二次谐波产生及压缩。290飞秒的输入脉冲在时间上被压缩至120飞秒,平均输出功率高达120毫瓦。将实验结果与一个数值模型进行了比较,该模型使用了通过频率分辨光学门控技术对输入脉冲进行表征所获得的数据。
