Abstract

By adding 14 mol % P2O5 to the core of a SiO2:Nd fiber, laser emission was obtained at 1.36 μm. From the fluorescent spectra and laser thresholds for the 4F3/2 to 4I11/2 and 4F3/2 to 4I13/2 transitions, the net gain at 1.36 μm is 0.024 dB/mW, and the ratio of excited-state absorption (the 4F3/2 to 4G7/2 transition) to stimulated emission is estimated to be 0.78.
