Abstract
A method for the laser probing of an imploding plasma in the S-300 high-current generator (current of 4 MA, impedance of 0.15 Ω and current rise time of 100ns) with the use of a YAG:Nd laser diagnostic setup is described. The setup enables the five-frame probing of the plasma with an exposure of 1 ns and an interval between frames of 10ns. Stimulated Brillouin scattering in carbon tetrachloride is used to compress the laser pulse of the master oscillator. Five stages of the second harmonic generators with optic delay lines form the intervals of the probing beams. Runs of shallow photographs of the plasma of wire liners and Z-pinches have been obtained.
