Research on performance promotion of plasma electrode Pockels cell

  • 摘要: 等离子体电极普克尔盒被广泛应用于大型激光驱动器中,用于抑制自激振荡、实现多程放大控制和反激光隔离,普克尔盒内的放电电极在长期使用过程中与腔内残余O2发生反应出现退化现象,导致稳定性下降,寿命降低。为此,提出了封离型等离子体电极普克尔盒,其放电腔内的Ne气浓度可达99.9%,漏率小于1.0×10−10 Pa m3∙s−1,理论使用年限大于40年。实验表明,封离型等离子体电极普克尔盒在工作20万发次后,其放电电极依然光亮如新,时间抖动仍稳定在6.4 ns附近,稳定性有了大幅提升。
