Glass fiber laser at 1.36 microm from SiO(2):Nd.
By adding 14 mol % P(2)O(5) to the core of a SiO(2):Nd fiber, laser emission was obtained at 1.36 microm. From the fluorescent spectra and laser thresholds for the (4)F(3/2) to (4)I(11/2) and (4)F(3/2) to (4)I(13/2) transitions, the net gain at 1.36 microm is 0.024 dB/mW, and the ratio of excited-state absorption (the (4)F(3/2) to (4)G(7/2) transition) to stimulated emission is estimated to be 0.78.
