Abstract: A compact Plasma Electrode Pockels Cell (PEPC) electrooptical switch will be used in beam reverser of multipass amplification system to control the output beam and restrain the selfoscillation produced by the multipass amplifier. In this paper, the performance of the compact PEPC electronoptical 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 electronoptical switch works well.-
