400 mW narrow linewidth single-frequency fiber ring cavity laser in 2 um waveband
T Yin, Y Song, X Jiang, F Chen, S He - Optics Express, 2019 - opg.optica.org
We present a single-frequency thulium-doped fiber laser (TDFL) with a narrow linewidth of
20 kHz. Stable single-longitudinal-mode (SLM) lasing operation at 1957 nm is achieved …
