| Abstract: | Coupled equations, governing variations of defining parameters of Gaussian beam propagating in logarithmically saturable nonlinear media, have been deduced from nonlinear propagational equations. Analytical soultions for coupled equations have been derived for cases where the incident Gaussian beams deviate slightly from the spatial soliton. General discussions have been made on the main characteristics of the Gaussian type breath mode formed in the nonlinear media. |
