Gaussian beam distortion caused by saturable gain or loss

Abstract

Results are given for the beam distortion suffered by low order Gaussian-Laguerre modes propagating through a saturable laser amplifier. Both uniform and Bessel small-signal gain distributions are considered. Beam narrowing caused by saturable loss is also treated.
