Abstract

This book discusses the consequence of the so-called self-focusing of a very short laser pulse in a transparent medium. Self-focusing is similar to focusing of a light/laser pulse by a lens except that this lens is a self-created one. If a laser pulse has an intensity distribution across the wave front and if the intensity is strong at the center and weak at the edge (a Guassian distribution in intensity, for example), the high intensity central part of the wave front would see a higher index of refraction in the medium due to nonlinear increase of the index of refraction than the low intensity edge. This is similar to focusing a plane wave by a lens where the central part passes through a thicker glass medium than the edge.
