报道了一种基于半导体可饱和吸收镜(SESAM)作为被动调Q激光器起始器和Yb：Lyso合金晶体作为增益材料的高效调Q激光器。在吸收泵浦功率为12.5W时，测得输出脉冲宽度约为7μ，脉冲链的平均功率约为0.92W，重复频率约为6.2 kHz。在此设置中还观察到Q开关锁模脉冲序列。激光性能测试表明，Yb：LiSO是一种很有前途的激光二极管泵浦紧凑型固体激光器的激光增益介质。
We report an efficient Q-switched laser action based on a semiconductor saturable absorber mirrors (SESAMs) as passively Q-switched laser starter and a Yb:LYSO alloyed crystal as gain material pumped directly by 974 nm In GaAs laser diodes. The output pulse duration is measured to be about 7μs, while the average power and the repetition rate of the pulse chain are about 0.92 W and 6.2kHz, respectively, under 12.5 W absorbed pumping power. The Q-switched mode-locked pulse train is also observed in this setup. The laser performance shows that Yb:LYSO is a promising laser gain medium for laser-diode pumped compact solid-state lasers.
