| Abstract: | Fiber lasers are of special interest for wide potential applications in all optical communication and other domains. Polarization effect is one of the most important factors on the output of fiber laser for PDG in EDFA. With the theoretical mechanism of the polarization saturation of the PDG, the PDG in the constant birefringence co efficient EDFA is derived based on a Fourier expansion carried out the distribution on the population inversion, and the gains for various optical fields under polarized states are calculated. Relations between the output spectrum and PDG are discussed. |
