Abstract
We present the first measurements of particle velocity histories at th e interface between an aluminum sample shocked by a 120 fs laser-drive n pressure pulse and a fused silica window. Frequency-domain interfero metry is used to provide space- and time-resolved measurements of the phase shift of a pair of probe pulses backscattered at the shocked int erface. Pressures of 1-3 Mbar are inferred from the simultaneous measu rement of the particle and shock velocities along the aluminum Hugonio t curve for similar to 10(14) W/cm(2) laser irradiances.
