Capjack, C. E., Birnboim, A., Rankin, Robert, Marchand, Richard
The effect of diffraction on the self‐modulation of an intense laser beam in an initially uniform hydrogen plasma is investigated. A formalism is used in which the diffraction term in the paraxial wave equation can be arbitrarily reduced by the use of a weight factor ι. In the limit where ι...

Rankin, Robert, Marchand, Richard, Capjack, C. E.
Two‐dimensional hydrodynamic simulations of laser light self‐focusing in a hydrogen plasma are presented. The simulation code includes a model for laser beam propagation which accounts for inverse bremsstrahlung absorption, refraction, diffraction, and ponderomotive forces. A Gaussian hot spot,...
