Coherently combined power of 20 W at 2000 nm from a pair of thulium-doped fiber lasers
Original language description
We experimentally demonstrated coherent beam combining of a pair of thulium-doped fiber lasers using an all-fiber Fox?Smith resonator. We built two thulium-doped fiber lasers from PM fibers and pumped them at 793 nm. Each laser provided a power of more than 10 W at a wavelength of 2000 nm with a slope efficiency of more than 0.5. Then a compound Fox?Smith resonator was created using the PM coupler. The obtained laser power was more than 20 W due to a constructive interference at the output of the laser,while the slope efficiency decreased to a value of 0.35. A stable CW output signal was achieved despite the fact that the individually operated lasers had the tendency to self-pulsate
