We report on a high-power diode-pumped (Yb:KGW) mode-locked laser with a semiconductor saturable absorber mirror (SESAM). For 32.7 W of incident pump power, we generate 261 fs pulses with the maximum average output power of up to 13.0 W and spectrum centered around 1039 nm at 68.4 MHz, corresponding to 190 nJ of single pulse energy and 0.72 MW of peak power. The optical-to-optical conversion efficiency is 39.8%, and the slope efficiency is 64.4%. The Yb:KGW laser exhibits a power stability better than 0.543% of the root-mean-square in 2 h.

飞秒激光在强场激光物理、超快化学动力学、微结构材料科学和生命科学等不同领域有着广泛应用。Yb:KGW晶体以其优异的综合性能适于作为飞秒激光器的增益介质，因此研究Yb:KGW飞秒激光器具有重要意义。自2000年瑞士研制出世界第一台被动锁模Yb:KGW飞秒激光器以来，国内外多家机构开展了Yb:KGW飞秒激光器的研究。主要报道了国内外Yb:KGW飞秒激光器的最新进展。目前能实现的最短脉冲宽度是100 fs，与理论值的47 fs还有一定的差距。
