摘要

本文采用连续钛宝石激光作抽运，掺杂浓度为6 at.%、长度为2.7 mm的Tm：YAG陶瓷作增益介质，通过引入半导体饱和吸收体获得了稳定的被动锁模运转. 实验中获得的激光锁模功率为116.5 mW，中心波长为2007 nm，重复频率为109 MHz，通过自行搭建的腔外非共线强度自相关测量得到的脉冲宽度是55 ps.

A passively mode-locked Tm:YAG ceramic laser was demonstrated. Employing a 6 at.% Tm3+-doped sample with a length of 2.7 mm, we have realized stable mode-locked pulses with a repetition rate of 109 MHz by a semiconductor saturable absorber. A maximum output power of 116.5 mW was obtained at the central wavelength of 2007 nm. The corresponding pulse duration was determined to be 55 ps by a self-built noncollinear intensity auto-correlation setup. It is shown that Tm:YAG ceramics are excellent laser materials which can be used in ultrafast lasers with high-power and high-efficiency output.
