Isolator-free unidirectional thulium-doped fiber laser [PDF]

Light: Science & Applications, 2015
We report the first demonstration of a unidirectional, isolator-free 2-mmthulium-doped fiber (TDF) laser, relying on the properties of the theta cavity (ring resonator with S-shaped feedback). The core pumped theta cavity TDF laser provides sub-Watt output power with a slope efficiency of 25%, a 2 dB flat tuning range of 1900–2050 nm, and a linewidth ...

Stretched-pulse operation of a thulium-doped fiber laser

Optics Express, 2008
We report on stretched-pulse operation of a thulium-doped fiber laser. The laser generated pulses at a center wavelength of 1974 nm with an energy of 4 nJ that could externally be compressed to a duration of 173 fs.

Kerr nonlinearity of Thulium-doped fiber near 2 μm

CLEO: 2015, 2015
The nonlinear coefficient and group velocity dispersion of a thulium-doped fiber near 2μm are evaluated via four-wave mixing. Nonlinearity of thulium-doped fiber can be used for the design of doped-fiber lasers in this spectral region.

Wavelength-Switchable Single-Longitudinal- Mode Thulium-Doped Fiber Laser With Sampled Fiber Bragg Grating

IEEE Access, 2021
A wavelength-switchable single-longitudinal-mode thulium-doped fiber laser using a sampled fiber Bragg grating is proposed in this study. The laser can be switched between three single-wavelength and three dual-wavelength modes of operation.

Mode-locked thulium-doped fiber laser with microfiber based polarization beam splitter

Results in Physics, 2020
We report on a passively mode-locked thulium-doped all-fiber laser utilizing our fabricated microfiber-based polarization beam splitters (PBSs). The all-fiber PBSs composed of two parallel and coupled microfibers are fabricated to separate light in two ...

Bound-State Soliton and Noise-like Pulse Generation in a Thulium-Doped Fiber Laser Based on a Nonlinear Optical Loop Mirror

Applied Sciences, 2022
We demonstrate a thulium-doped, mode-locked, all-fiber laser capable of operating in two generation regimes: dispersion-managed soliton and noise-like pulse (NLP).
