Abstract

We present an ultra-widely tunable non-collinear optical parametric oscillator with an average output power of more than 3 W and a repetition frequency of 34 MHz. The system is pumped by the second harmonic of a femtosecond Yb:KLu(WO4)2 thin-disk laser oscillator. The wavelength of the signal pulse can be rapidly tuned over a wide range from the visible to the NIR just by scanning the resonator length.

摘要

我们展示了一种超宽可调谐非共线光学参量振荡器，其平均输出功率超过3W，重复频率为34MHz。该系统由飞秒Yb:KLu(WO4)2薄片激光振荡器的二次谐波泵浦。仅通过扫描谐振器长度，信号脉冲的波长就可以在从可见光到近红外的很宽范围内快速调谐。
