Propagation of intense CW-light through a strongly absorbing medium - Self-focusing and spatial ringings
Abstract
It is shown that the intensity of a CW light propagating through strongly absorbing media is highly nonlinear with respect to the incident one for both high-input intensities and large absorption. The order of nonlinearity can reach a value whose magnitude is of the order of the product of the cell length and the absorption length. An analytical treatment of the transverse effects for an input Gaussian profile pulse is proposed for the case of a strongly nonlinear regime. The study seeks to describe the transverse distortions of a CW input Gaussian cross section beam when it propagates through a strongly absorbing medium.
