Abstract

A theoretical analysis of a three-level fiber laser amplifier in the small-signal regime is presented in which the effects of the transverse variation of the pump and signal mode intensities, the transverse variation of the density of the lasing species, and excited-state absorption of pump photons are included. Guidelines for the design of an optimum fiber are given.
