OPTICAL FEEDBACK EFFECTS IN ND-DOPED FIBER LASERS WITH BROADBAND SPECTRA

摘要

A detailed experimental and theoretical investigation of optical feedback effects in Nd-doped fiber lasers is presented. Of particular interest is an output-intensity reduction attributed to the broadband nature of the laser spectrum combined with a mode-selection mechanism of the external Fabry-Perot cavity. The theoretical approach, based on a simple multimode rate-equation model, provides an excellent description of the experimental results. (C) 1996 Optical Society of America [References: 10]
