Chirped pulse reflectivity and frequency domain interferometry in laser driven shock experiments

We show the simultaneous applicability of the frequency domain interferomet ry and the chirped pulse reflectometry techniques to measure shock paramete rs. The experiment has been realized with the laser at the Laboratoire pour l'Utilisation des Lasers Intenses (LULI) with a 550-ps pulse duration and an intensity on target similar to 5 x 10(13) W/cm(2) to produce a shock in a layered aluminum-fused silica target. A second low energy, partially comp ressed chirped probe beam was used to irradiate the target rear side and th e reflected light has been analyzed with a spectrometer, achieving a tempor al resolution of the order of 1 ps. [S1063-651X(99)50509-6].
