Wang, J., Lin, S., Liang, X., Wang, M., Yan, P., Hu, G., Albrow-Owen, T., et al. (2017). High-energy and efficient Raman soliton generation tunable from 1.98 to 2.29 µm in an all-silica-fiber thulium laser system. Optics Letters, 42 (18), 3518-3521. https://doi.org/10.1364/OL.42.003518
We demonstrate a compact, all-fiber-integrated laser system that delivers Raman solitons with a duration of ~100 fs and pulse energy of up to 13.3 nJ, continuously wavelength tunable from 1.98 to 2.29 µm via Raman-induced soliton self-frequency shift (SSFS) in a thulium-doped fiber amplifier. We realize a >90% efficiency of Raman conversion, the highest reported value from SSFS-based sources. This enables us to achieve >10 nJ soliton energy from 2.16 to 2.29 µm range, the highest energy demonstrated above 2.22 µm from an SSFS-assisted all-fiber tunable single-soliton-pulse source. Our simple and compact all-fiber tunable laser could serve as an efficient ~2 µm femtosecond source for a wide range of mid-IR applications.
