A single-oscillator monolithic thulium-doped fiber laser in which the 793 nm core absorption of 8.42 dB/m allows emitting 193 W (46 % of slope efficiency) at $2.09~\mu \text{m}$ is presented. An 8°-cleaved angle of the fiber facet suppresses the parasitic cavity that formerly limited the power scaling. The characteristics of the thulium laser operating at the uncommon 2.09- $\mu \text{m}$ long wavelength is compared to the power performances of a similar thulium-holmium codoped fiber laser. |
