Characterizations of symmetry and asymmetry high-density gas jets without Abel inversion

Abstract

Characterizations of the high-density gas jets are performed for the laser-gas interaction. It is shown that the gas density profile can be obtained without the Abel inversion, when a Gaussian distribution is assumed. In addition, a rectangular nozzle is characterized for the long plasma generation. In this case, the Boltzmann distribution is introduced for the density profile and its result shows a good agreement with the experimental result. (C) 2004 American Institute of Physics.
