| 摘 要： | 采用外腔式电光开光,调制主动照相探测光源,使光电倍增管处于脉冲工作状态下,以提高光电倍增管的输出幅度和动态范围,改善信号的信噪比,同时避免样品和探测器受长时间强激光照射.对滨松H6780光电倍增管进行了调试,使其线性输出电流由静态的0.1mA提升到脉冲状态的4.4mA,信噪比提高4.5倍.该技术对其他光敏探测有借鉴意义.

| 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. |
