摘要: 设计建造了通光口径为240mm×240mm等离子体电极普克尔盒，在KDP的两侧用磁控阴极放电产生了覆盖全口径的等离子体电极。用仿真线成形，产生了电压幅值10kV，脉冲上升时间50ns，脉宽500ns，顶部电压波动＜±2%的矩形开关脉冲。测得电光开关的光学特性为全口径静态透过率85.8%,静态消光比132，开关效率97.6%，开关上升时间95ns。Abstract: A 240mm×240mm plasma electrode Pockels cell is constructed. Using a planer magnetron cathode a uniform plasma discharge covered the full aperture on either side of the KDP crystal is produced. A rectangular switch pulse with 50ns rise time,500ns pulse width and ≤±2% surge in the top platform is shaped by a pulse forming network. Measurements of the optical performance show that the static transmittance of 85.8%, extinction ratio of 132, switching efficiency of 97.6% and switching rise time of 95ns are obtained.
