Abstract The propagation of short-pulse lasers through several Rayleigh lengths of underdense plasma [(1{endash}4){percent} {ital n}{sub cr}] is studied using multidimensional fully explicit particle-in-cell simulations. The simulations model 80 to 600 fs, 1 {mu}m wavelength pulses in the intensity range of 1.5{times}10{sup 17} to 3.5{times}10{sup 19} W/cm{sup 2}. 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}{ital 1996 The American Physical Society.}
