Abstract

Two high power, broadband, 1.55 µm sources utilizing an erbium-doped silica-based single mode fiber pumped at 0.5145 p.m are presented. The first source is a non resonant superfluorescent fiber laser. With proper selection of the fiber length, it exhibits an output power of 5 mW and a bandwidth of 19 nm for an absorbed pump power of 460 mW. Spectral variations with pump power and/or fiber length, in particular spectral shape, center wavelength and spectral narrowing, are investigated. The second source is a resonant fiber laser with an intracavity acousto-optic modulator which, when frequency modulated at a rate lower than 1 kHz, produces modulation of the laser wavelength over 9 nm with an output power in excess of 5 mW.
