Abstract
We report a novel short-length diode-pumped cw fiber laser with high output
power at a wavelength of 2.8 mu m. The system combines continuous-wave dio
de pumping at 970 nm, a high doping concentration (5-mol. % ErF3) of the ac
tive fiber, and an annular geometry of the laser medium, an M-profile fiber
. Output powers in excess of 1 W with a slope efficiency of 25% were obtain
