Stochastic (i.e. random and quasi-random) optical fields may contain distributions of optical vortices that are represented by non-uniform topological charge densities. Numerical simulations are used to investigate the evolution under free-space propagation of topological charge densities that are inhomogeneous along one dimension. It is shown that this evolution is described by a diffusion process that has a diffusion parameter which depends on the propagation distance.

Author:West, NJ; Jandrell, IR; Forbes, ADate:Aug 2008The aim of this paper is to compare the electrical performance of an orthogonally with a coaxially laser-triggered spark gap. Each of these two gaps has its own advantages and disadvantages. At the same time, a Rogowski profile spark gap was ...Read more
