Abstract
The need for ultrafast 2-D diagnostic techniques for studying laser produced plasmas led to the development of picosecond framing cameras. Up to now, several approaches have been investigated and some progress has been achieved.1–5 We have recently developed and tested a picosecond framing camera. The experimental results have shown that this camera can provide, we believe for the first time, six-frame 7 × 7-mm2 images with an exposure time of 40 ps (FWHM), a framing rate of 6.25 × 109 frames per second, and a dynamic spatial resolution of 5.5 lp/mm. To our knowledge these results are the best at present. To achieve these performances two devices were developed: a specially designed picosecond framing image tube and a novel photo-conductive switch pulse-forming network.
