Watt-level visible laser in double-clad Pr3+-doped fluoride fiber pumped by a GaN diode

Watt-level visible laser in double-clad Pr3+-doped fluoride fiber pumped by a GaN diode

We report on a red praseodymium fiber laser delivering 1.07 W at 634.5 nm with a slope efficiency of 20.7% (versus the incident pump), a laser threshold of 0.55 W, and a single-mode output (M2x,y
