等离子体电极电光开关是大口径高功率固体激光器的关键技术之一。利用厚度为15 mm的KDP晶体研制了口径为240 mm×240 mm的金属壳体开关, 测试结果表明其主要指标达到了驱动器总体的要求。对目前的几种应用方法进行了对比研究。

Plasma-electrode electro-optic switch is one of key technologies for largely aperture high power solid laser. A metallic chamber plasma-electrode electro-optic switch with clearly aperture of 240 mm by 240 mm with a KDP crystal slab which is 15 mm thickness. Its switch efficiency is larger than 98%. Comparing to the other switch, the compounding model has better performance.
