Abstract

We report on a laser system capable of generating high-energy (>270 mJ) temporally shaped pulses at 1064 nm with 0.43-ns shaping resolution. The pulses are generated by modulation of a continuous-wave seed laser and subsequent amplification by a dual-stage grazing-incidence Nd:YVO4 "bounce" amplifier and a Nd:YAG power amplifier (all quasi-continuous diode-pumped). The system produces pulses with a high-quality top-hat spatial beam profile with up to 0.6 GW of peak power and 44 W of average power, a power stability of 0.22% rms, and fully programmable complex temporal shapes.

摘要

我们报道了一种激光系统，该系统能够在1064nm波长下产生能量高于270 mJ的具有时间整形的脉冲，整形分辨率为0.43 ns。这些脉冲通过对连续波种子激光进行调制，随后由双级掠入射Nd:YVO4“反射”放大器和Nd:YAG功率放大器（均为准连续二极管泵浦）进行放大产生。该系统产生的脉冲具有高质量的平顶空间光束轮廓，峰值功率高达0.6GW，平均功率为44W，功率稳定性为0.22% rms，并且具有完全可编程的复杂时间形状。
