Use of laser lighted photoconductive cells

The way of understanding laser matter experiments is to use specific instrumentation which needs new techniques, in terms of triggering, fast high voltage ramps generation and fiducial, using fast optoelectronic switches. Some experiments realized around large lasers as Phebus and P102 installed on the CEA-Limeil-Valenton center and described in this paper illustrate the possible applications of these cells for the always more exacting requirements of the physics of the condensed plasmas.
