Abstract
Many theoretical and computer simulation results have been published recently involving the interaction of short pulse, high intensity lasers with underdense plasmas.1-4 This is a new regime in which to study laser-plasma interactions since the length of the laser pulse is shorter than the Rayleigh range of the laser and the length of the plasma (cτL< LR, Lp). Developments in laser technology over the last several years have made the experimental investigation of this regime possible. In this paper, we describe the first experimental observation of forward stimulated Raman scattering and energetic electrons from the interaction of a subpicosecond, high intensity laser with an underdense plasma.
