摘　　要：对激光二极管端面泵浦Nd:YAG激光器的热效应进行了分析.由热传导方程得出YAG晶体内的温度分布,模拟出激光晶体的折射率分布,并得到了激光束腰和YAG的热焦距随泵浦功率的变化曲线.The thermal effect of laser diode end_pumped Nd:YAG laser are studied. The temperature distribution in YAG crystal is obtained by heat exchange equation. The refractive index distribution in laser crystal is simulated. The figures of laser waist and thermal focus length dependence on pump power are received, too.
