Abstract
Small-signal amplification on the 3P0 3F2 transition in a praseodymium-doped fluorozirconate optical fiber at the 632.8-nm He-Ne wavelength, has realized a slope efficiency of 0.15 dB mW and up to 14 dB gain. Spectroscopic and fiber parame ters, including the pump absorption cross section (sigma a 0.14 0.02 10 24 m2), p the signal emission cross section (sigma e 2.1 0.2 10 24 m2), and the 3P state ( ) s 0 lifetime tau 3 49.8 0.3 mus , determined experimentally, independently of the gain, were used to model the performance of the amplifier. The predictions of the rate equation model were in good agreement with the measured gain.
