Abstract

We developed a laser-diode pumped, 4.6-GHz repetition-rate, Yb:KYW Kerr-lens mode-locked femtosecond oscillator. A bow-tie ring cavity generates an output power of 14.6 mW with a spectrum width of 11 nm at 1046 nm. To the best of our knowledge, this is the highest-repetition frequency in the laser-diode pumped femtosecond Kerr-lens mode-locked laser.

摘要

我们研制了一种激光二极管泵浦、重复频率为4.6 GHz的Yb:KYW克尔透镜锁模飞秒振荡器。一个蝴蝶结形环形腔在1046 nm处产生14.6 mW的输出功率，光谱宽度为11 nm。据我们所知，这是激光二极管泵浦飞秒克尔透镜锁模激光器中最高的重复频率。
