Abstract

When a high power laser irradiates a thin foil, its back surface is accelerated to several km/sec. Due to hydrodynamic instabilities the foil is broken into pieces. This ejected material form an Aluminum target was recorded, using off-axis holography technique. The main laser that generates the shock wave, is a Nd:YAG laser system with a wave length of 1.06 micrometers , pulse duration of 7.5 ns and irradiance in the range (1.4-2.4) by 10¹³ W/cm². The hologram is produced by splitting a frequency doubled beam of an additional laser, synchronized with the main laser. One part of it is used as the object beam and the second part serves as the reference beam to the hologram.
