在二极管泵浦的Nd，Cr：YAG激光器中实现了同时的自调Q和锁模。首次在腔内光强为5.6× 105 W/cm ~ 2时获得了几乎100%的调制深度。在1064 nm处获得了6.52W的最大平均输出功率，对应于30%的斜率效率。在泵浦功率为16.5W时，获得了高质量的TEM 00模脉冲。锁模脉冲的脉宽约为600 ps，重复频率为136 MHz。
Simultaneous self-Q-switched and mode-locked have been demonstrated in a diode-pumped Nd,Cr:YAG laser. For the first time as we know, almost 100% modulation depth has been achieved at an intracavity intensity of 5.6×105W/cm2. The maximum average output power of 6.52W corresponding to a slope efficiency of 30% is obtained at 1064nm. The laser produces high-quality pulses in a TEM00-mode at the pump power of 16.5W. The pulse duration of the mode-locked pulses is about 600ps with 136MHz repetition rate.
