Abstract

We report on the generation of sub-30 fs pulses from a diode-pumped Yb,Gd:YAP laser. Using soft-aperture Kerr-lens mode-locking, soliton pulses as short as 23 fs were achieved at 1082.3 nm, with an average output power of 45 mW at a repetition rate of 67.25 MHz. The mode-locked laser also produced a maximum average output power of 101 mW at 1056.5 nm with a slightly longer pulse duration of 34 fs, corresponding to a peak power of 38.9 kW. To the best of our knowledge, this is the first demonstration of Kerr-lens mode-locked operation in a diode-pumped Yb,Gd:YAP laser, with the shortest pulses ever reported from any Yb-doped perovskite-type crystal.

摘要

我们报道了从二极管泵浦的Yb，Gd：YAP激光器产生亚30 fs脉冲的情况。使用软孔径克尔透镜锁模，在1082.3 nm处实现了短至23 fs的孤子脉冲，重复频率为67.25 MHz时平均输出功率为45 mW。锁模激光器在1056.5 nm处还产生了101 mW的最大平均输出功率，脉冲持续时间稍长，为34 fs，对应峰值功率为38.9 kW。据我们所知，这是二极管泵浦Yb，Gd：YAP激光器中克尔透镜锁模运行的首次演示，也是从任何掺Yb钙钛矿型晶体中报道的最短脉冲。
