Abstract
Optical amplification at the 632.8 nm He-Ne wavelength has been investigated in praseodymium-doped fluorozirconate fiber. A slope efficiency of 0.15 dB/mW was realized with up to 14 dB gain which is a significant improvement on previously reported results. A rate equation approach is used to model and understand the gain dynamics. The lifetime of the 3P0 state was measured to be 46.5 +/- 0.9 microsecond(s) . Using Fuchtbauer-Ladenburg analysis, the absorption cross-section at the pump wavelength and the emission cross- section at the signal wavelength were calculated to be 0.39 +/- 0.03 pm2 and 1.65 +/- 0.15 pm2 respectively.
