High-dynamic-range laser-pulse-contrast measurement with a plasma-shuttered streak camera

摘要

The dynamic range of a picosecond visible streak camera has been improved by the combination of a plasma shutter and multishot averaging performed with a photoconductive switch Sweep circuit. We use this technique to measure the contrast of a 100-fs laser pulse over 2 ns with a dynamic range of 7 orders of magnitude. (C) 1997 Optical Society of America.
