我们目前正在研制一种高效率的Yb：YAG再生放大器，由连续二极管激光器泵浦。通过理论计算对再生放大器的性能进行了估计。对于激发过程，速率方程数值积分的重复间隔与CW泵浦。对于再生脉冲放大过程，将Frantz-Nodvik方程应用于每次通过。将理论计算结果与重复频率为10 kHz、输出脉冲能量为2 mJ的实验数据进行了比较。获得了17.8%的光-光转换效率。还提到了正在为商业产品开发的原型的轮廓
We are currently developing a high-efficiency Yb:YAG regenerative amplifier pumped by CW diode lasers. The performance of the regenerative amplifier was estimated by theoretical calculations. For the excitation process, a rate equation was numerically integrated over the repetition interval with CW pumping. For the regenerative pulse amplification process, the Frantz-Nodvik equation was applied for each pass. The result of the theoretical calculation was compared with experimental data of a 2 mJ output pulse energy at a 10 kHz repetition rate. An optical-optical conversion efficiency of 17.8% was achieved. The outline of a prototype under development for a commercial product is also mentioned
