采用激光二极管(LD)抽运Cr4+:YAG被动调Q内腔式PbWO4锁模拉曼激光器获得了稳定的、调制深度为100%的调Q锁模拉曼脉冲。抽运功率为6.3 W时，获得的锁模拉曼激光输出功率为582 mW，抽运光到一阶斯托克斯光的转换效率为9.24%，斜效率为10.6%，调Q脉冲重复频率为41.3 kHz，脉宽为6 ns，锁模脉冲重复频率为1.1 GHz，锁模脉冲宽度小于207 ps。

A laser-diode-pumped Cr4+:YAG passively Q-switched intracavity PbWO4 mode-locked Raman laser is demonstrated. Stable and Q-switched mode-locked laser output of modulation depth 100% is realized. A maximum average output power of 582 mW is obtained when the incident pump power is 6.3 W corresponding to an overall pump light-first-order Stokes conversion efficiency of 9.24% and a slope efficiency of 10.6%. The Q-switched pulse with repetition rate of 41.3 kHz and pulse width of 6 ns is obtained. The width of the mode-locked pulse is estimated to be less than 207 ps with 1.1 GHz the repetition rate of 1.1 GHz.
