Abstract: Electro optic shutter was employed to modulate the illuminating laser in VISAR test for several reasons,1) To increase the output amplitude of photomultiplier,2) To make the photomultiplier′s dynamic range wider,and 3) To avoid the photomultiplier and target from lighting of the laser too long.In fact this electro optic shutter was used on H6780 photomultiplier,and the photomultiplier′s maxium current improved from 0.1mA to 4.4mA with S/N enhanced 4.5 times.This result has practical sense.
