Abstract
Coherent electromagnetic wave amplifiers with nonnegligible gain per wavelength are included in the Gaussian beam matrix formalism and a procedure is developed for propagating Gaussian beams in optical systems that may include unsaturated amplifiers and similar absorbers. Standard formulas for beam spotsize and radius of curvature in a uniform medium are generalized in a new way to include gain or loss. An asymmetric focal shift and a potentially infinite spotsize are predicted, These dramatic effects are interpreted physically.This publication has 28 references indexed in Scilit:
