利用一片GTI镜补偿腔内色散，并使用宽带半导体可饱和吸收片，实现了锁模自启动的飞秒Cr4+:YAG激光输出.在9W平均功率的1030nm激光抽运下，获得输出脉冲功率为95 mW，光谱半高全宽45 nm，中心波长1508 nm，实测脉冲宽度为65 fs.

A self-starting mode-locked Cr4+:YAG laser is reported, which incorporates a broadband SESAM and uses a piece of GTI mirror to compensate the intra-cavity group-delay dispersion. 65-fs pulses are generated at an average power of 95 mW with a 45 nm spectral bandwidth centered at 1508 nm under the pump power of 9 W.-
