摘要

我们报告了工作波长为 2090 nm、由多模光纤耦合 793 nm 激光二极管泵浦的被动锁模 Tm,Ho:CLNGG 激光器，这是首次演示 2.1 μm 波长的二极管泵浦亚 100 fs 锁模激光器。由于增益材料的无序性，其增益曲线宽而平滑，因此在 70.3 MHz 的重复频率下实现了短至 88 fs 的脉冲，平均输出功率为 120 mW。利用基于砷化镓材料系统的半导体可饱和吸收镜，实现了稳定的自启动模式锁定运行。

Diode-pumped 88 fs SESAM mode-locked Tm,Ho:CLNGG laser at 2090 nm

We report on a passively mode-locked Tm,Ho:CLNGG laser operating at 2090 nm, pumped by a multimode fiber-coupled 793 nm laser diode, representing the first demonstration of a diode-pumped sub-100-fs mode-locked laser at 2.1 μm wavelength. Due to the disordered nature of the gain material that exhibits a broad and smooth gain profile, pulses as short as 88 fs were achieved with an average output power of 120 mW at a repetition rate of 70.3 MHz. Stable self-starting mode-locked operation was obtained using a semiconductor saturable absorber mirror based on the GaSb material system.
