Description
The propagation of short-pulse lasers through several Rayleigh lengths of underdense plasma [(1 endash 4)% ncr] is studied using multidimensional fully explicit particle-in-cell simulations. The simulations model 80 to 600 fs, 1 μm wavelength pulses in the intensity range of 1.5x1017 to 3.5x1019 W/cm2. A detailed account is given for the energy lost out of the focal cone due to a combination of collective absorption and scattering losses. The figure of merit for the nonlinear transmission losses of a given pulse length is the amount of Raman forward scattering exponentiation within a Rayleigh length. copyright 1996 The American Physical Society
