摘要
This paper presents results obtained in an experiment performed at the LULI 2000 laser facility where we measured saturated Stimulated Raman Scattering (SRS) in a supersonic gas jet of ethylene (C2H4). Our conditions correspond to the following parameters: k(EPW)lambda(D) = [0.2-0.3], T-e = [0-1] keV and n(e) = [1.2-10] % of critical density at 526 nm. The laser was smoothed with a random phase plate and had a maximal average intensity of 1.2x10(15) W/cm(2) in the focal spot.
