报道了高功率二极管泵浦的Nd：GGG激光器的连续波(CW)和被动调Q特性。在泵浦功率为14.97W时，获得了7.20W的连续输出功率，斜率效率为52.7%。采用掺铬铝石榴石晶体作为可饱和吸收材料，获得了最短的被动调Q脉冲宽度为7.7 ns，最大脉冲能量为126.25μJ，最大峰值功率为15.5kW。
We report on the continuous wave (CW) and passive Q-switching performance of a high-power diode-pumped Nd:GGG laser. A CW output power of 7.20 W was obtained under an absorbed pump power of 14.97 W, which gives a slop efficiency of 52.7%. With a Cr4+ doped yttrium aluminum garnet crystal as the saturable absorber, the shortest passively Q-switched pulse width, largest pulse energy, and highest peak power achieved were 7.7 ns, 126.25 μJ, and 15.5 kW, respectively.
