Abstract

A high-power red fibre laser with a Pr-doped waterproof fluoro-aluminate glass fibre (Pr:WPFGF) is reported. Even though a Pr:WPFGF is a fluoride material, it possesses low deliquescence and enough long-term stability. A blue/violet GaN laser diode at 442nm was launched into the Pr:WPFGF (core diameter 8m, length 40mm), both end surfaces of which were directly coated to construct a resonator. The maximum output power was measured to be 311.4mW at 800mW pumping power. The oscillation wavelength was 638nm and the slope efficiency was calculated to be 41.6. These results showed good agreement with theoretical predictions.
