摘　　要：基于激光跃迁截面、荧光寿命、光学机械系数和抗击热应力能力的分析,表明Nd:YAlO_a晶体与Nd:Y_3Al_5O_(12)晶体一样,是发展高功率连续固体激光的有用晶体。利用φ7×155nm的Nd:YAlO_3晶体己得到了424W1079.5nm连续激光,器件总效率2.54％,斜率效率为3.77％。On the basis of analysis and contrast for the stimulated emission cross section the fluorescent lifetime and optomechanical coefficient as well as the ability to resist the thermal stress, it is shown that similar to the Kd: Y3A15O12 crystal the Nd: YAlO3crystal is a useful material to develop high power CW solid state lasers. 424W output power with an overall efficiency of 2.54% and a slope efficiency of 3.77% have been achieved from a 7 X155mm Nd:YABO3 rod.
