Phys. Rev. E 77, 026408 (2008) [8 pages]Fast electron transport and induced heating in solid targets from rear-side interferometry imagingReceived 18 July 2007; published 25 February 2008 Fast adiabatic plasma heating of a thin solid target irradiated by a high intensity laser has been observed by an optical fast interferometry diagnostic. It is driven by the hot electron current induced by the laser plasma interaction at the front side of the target. Radial and longitudinal temperature profiles are calculated to reproduce the observed rear-side plasma expansion. The main parameters of the suprathermal electrons (number, temperature, and divergence) have been deduced from these observations. © 2008 The American Physical Society URL:
