【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 cr ystal is produced. A rectangular switch pulse with 50ns rise time,500ns pulse wi dth and ≤±2% surge in the top platform is shaped by a pulse forming network. M easurements of the optical performance show that the static transmittance of 85. 8%, extinction ratio of 132, switching efficiency of 97.6% and switching rise ti me of 95ns are obtained.更多还原
