Tunable wavelength-stabilized mode-locked thulium-doped fiber laser beyond 2000nm

, 2022
We demonstrate operation of a tunable mode-locked thulium-doped fiber laser, based on a wavelength-selective chirped fiber Bragg grating (CFBG). By applying strain to the CFBG, we shift its reflection band and can thereby tune the emission-wavelength of ...

Wavelength-Spacing Adjustable Dual-Wavelength Dissipative Soliton Resonance Thulium-Doped Fiber Laser

IEEE Photonics Journal, 2019
A dual-wavelength dissipative soliton resonance thulium-doped fiber laser based on nonlinear optical loop mirror (NOLM) has been demonstrated. In this laser, mode-locking is achieved based on equivalent saturation absorption of the NOLM, while the dual ...

Ureteroscopy with thulium fiber laser lithotripsy results in shorter operating times and large cost savings

World journal of urology, 2022
Prolonged ureteroscopy (URS) is associated with complications including ureteral perforation, stricture, and urosepsis. As laser lithotripsy is one of the most common urologic procedures, small cost savings per case can have a large financial impact ...

High power cladding-pumped Raman fiber laser with true single-mode output at 1660 nm

, 2006
We report a 10 W continuous-wave cladding-pump Raman fiber laser with single-mode output at 1660 nm pumped by a high-power Er:Yb fiber amplifier. The laser threshold was 6.5 W and its slope efficiency was 67%

Monolithic narrow linewidth polarization-maintaining thulium fiber laser using femtosecond laser written fiber Bragg gratings

, 2022
Paper 80390HWe have demonstrated an all-fiber thulium laser system that, without any intracavity polarizing elements or freespace components, yielded a stable polarization extinction ratio (PER) of ?18 dB.
