Abstract

Rare-earth-doped single mode fibers have been made into superfluorescence light sources, of interest for signal-processing fiber systems, atomic physics and sensor technologies; especially in fiber optic gyroscopes the broad linewidth is important as is higher output power and better wavelength stability. Nd³⁺-doped¹ and Er³⁺- doped² superfluorescence fiber light sources have been demonstrated. We report the results of a superfluorescence Pr³⁺-doped silica-based fiber light source at 1048 nm on the ¹D₂-³F_3,4 transition. The output power, linewidth and stability of the intensity- weighted average wavelength versus pump power are investigated.
