| 摘 要： | 为提高固体激光器的能量利用率，增大输出能量，将双掺Nd:Ce:YAG晶体的输出特性与普通Nd:YAG晶体进行了对比研究。分析了Nd3+和Ce3+的吸收光谱对激光晶体初始阈值反转粒子数的影响，结果显示:双掺Nd:Ce:YAG晶体可以提高晶体对泵浦光能量的利用率及激光器的输出能量，且可降低阈值泵浦能量。并分别检测了Nd:Ce:YAG激光晶体与Nd:YAG晶体的输出激光能量和阈值泵浦能量，实验结果表明：在输入电压为750 V时，Nd:Ce:YAG晶体与Nd:YAG晶体的输出能量分别为651.5 mJ 和390.4 mJ，能量利用率分别为2.31%和1.38%，激光振荡需要的泵浦能量阈值分别为10.56 mJ和15.21 mJ，且普通Nd:YAG晶体的斜效率为0.36%，而双掺Nd:Ce:YAG晶体的为0.49% 。

| Abstract: | In order to increase the energy efficiency and output energy of solid lasers,the output characteristics of Nd:Ce:YAG crystal was studied,compared with simple Nd:YAG crystal.The impact on initial inverted population caused by the absorption spectrum of Nd3+ and Ce3+ was analyzed.It is found that the energy efficiency of laser crystal can be increased by doping both Nd3+ and Ce3+ in YAG crystal,which increases the output energy and lowers the threshold pump energy of lasers.With the same input voltage of 750 ... |
