高功率激光 能源系统 引燃管 自闪 同轴结构 High power laser Power conditioning system Iignitron Prefire Coaxial structure
摘要
分析了高功率固体激光能源系统新型放电回路中引燃管的自闪原因,提出引燃管同轴安装结构,利用同轴结构的负反馈作用,把放电电流控制在引燃管中央;同时利用同轴结构的电场屏蔽作用,进一步减少水银在管壁的凝结.在4×2×3片状放大器2000发次的运往中,引燃管没有发生自闪现象.
Abstract
This paper analyzes the mechanism that ignitron prefires when it is used in new discharge circuit of power conditioning system for high power laser. The performance of ignitron is improved with a coaxial structure. The coaxial structure not only controls discharge current flowing through the center of ignitron but also shields the electric field produced by the ignitron. The ignitrons have successfully run over 2 000 shots in 4×2×3 amplifier system without prefire.
