PEPC electrooptical switch used in beam reverser of multipass amplifier

A compact Plasma Electrode Pockels Cell (PEPC) electrooptical switch will be used in beam reverser of multipass amplification system to control the output beam and restrain the selfoscillation produced by the multipass amplifier. In this paper, the performance of the compact PEPC electronoptical switch and its application in multipass amplification system are described in detail. Measurements of the optical performance show static transmittance of 94%, switching efficiency of 98.9%. The experimental result in multipass amplifier indicates that the PEPC electronoptical switch works well.
