Effect of Diffusion on Laser Induced Breakdown of Gases.

Abstract

A variational method has been developed to account for the effect of diffusion on laser induced breakdown. The method is applicable for arbitrary distributions of intensity in the focal volume. It has been specifically applied to the calculation of breakdown for Gaussian spots, and found to yield breakdown intensities differing by nearly a factor of 2 from calculations employing simplified diffusion models.
