We report a palm-top-size femtosecond diode-pumped mode-locked Yb(+3):KY(WO(4))(2) solid-state laser with a semiconductor saturable absorber mirror utilizing soliton mode locking for shortening the cavity to 50 mm. An average output power of 680 mW and a pulse width of 162 fs were obtained at 1045 nm with a repetition rate of 2.8 GHz, which led to a peak power of 1.5 kW. Average power fluctuations of a modularized laser source were found to be +/-10% for the free-running 3000 h operation and +/-1% for the power-controlled 2000 h operation.
我们报告了一种手掌大小的飞秒二极管泵浦锁模 Yb(+3):KY(WO(4))(2) 固态激光器，采用半导体可饱和吸收镜实现孤子锁模，将腔长缩短至 50mm。在 1045nm 处，重复率为 2.8GHz 时，获得了平均输出功率为 680mW 和脉冲宽度为 162fs 的结果，从而产生了 1.5kW 的峰值功率。对于自由运行 3000 小时的模块化激光源，平均功率波动发现为 +/-10%，对于功率控制 2000 小时的运行，平均功率波动发现为 +/-1%。
