Modeling of polarization effects in fiber lasers

J.T.Lin, W.A.Gambling, D.N.Payne

Abstract

Experimental investigation of various fiber lasers containing rare earth ions shows that the polarization effects with a Fabry-Perot cavity can be characterized by three basic factors: The fluorescence caused by spontaneous emission is depolarized independently of the polarization of the pump light. Two orthogonal phase independent polarization eigenmodes exist in the single-mode fiber laser cavity. The polarization state of the output from the fiber laser depends on the orientation of the pump light polarization, pump power level, and dopant characteristics. The evidence of polarization effects in a Nd3+ doped fiber laser can be clearly seen from Figs. 1 and 2 and Ref. 1.
