摘要

本文首次展示了基于 Yb:CALYO 晶体的腔倾销 Kerr 透镜模式锁定飞秒振荡器。在 SESAM 的帮助下，克尔透镜锁模 Yb:CALYO 激光器在 61.3 MHz 的重复频率下发出了平均功率为 2.8 W 的脉冲，对应的脉冲能量为 45.6 nJ。通过使用由双 β-BBO 晶体和薄膜偏振器组成的 Pockels Cell 进行空腔倾卸，在 1 MHz 和 10 kHz 重复频率下均可获得 280 nJ 的激光脉冲。测量到的最短脉冲持续时间为 233 fs，没有外部压缩，峰值功率为 1.06 MW。

Cavity-dumped femtosecond Yb:CALYO laser based on SESAM assisted Kerr-lens mode locking

In this paper, we present the demonstration of a cavity-dumped Kerr-lens mode-locked femtosecond oscillator based on an Yb:CALYO crystal for the first time. With the assistance of an SESAM, the Kerr-lens mode-locked Yb:CALYO laser delivered pulses with an average power of 2.8 W at a repetition rate of 61.3 MHz, corresponding to a pulse energy of 45.6 nJ. By employing a Pockels Cell consisting of dual β-BBO crystals and a thin film polarizer for cavity dumping, laser pulses of 280 nJ were achieved at both 1 MHz and 10 kHz repetition rates. The shortest pulse duration measured was 233 fs without external compression, resulting in a peak power of 1.06 MW.
