Abstract

A theory based on the field and non-linearity expansions interms of Laguerre-Gauss functions is presented. The theoryi useful when very fast self focusing occurs, as in the case of relativistic self focusing. Results for self trapping with a saturable non-linearity are closer to the numerical results than those obtained by any other theory.
