A Numerical Calculation of Thermal Blooming of Pulsed, Focused Laser Beams
Abstract
The report summarizes the development of a computer program which solves the problem of propagation of pulsed, focused laser beams in a gas. The code includes the effects of the absorbing medium by self-consistent inclusion of the detailed hydrodynamic processes. The report presents a description of the transformations of the relevant equations, a description and stability analysis of the algorithms used, a summary of the checks on accuracy and internal consistency both of the wave optics and the hydrodynamics, comparison with analytic theories, and presentation of an example of results for a typical case of interest.
