Adoption of thulium fiber laser for lithotripsy
Canadian Urological Association JournalIntroduction: While Holmium:YAG for laser lithotripsy remains the gold standard, the thulium fibre laser (TFL) has gained traction as a tool in urolithiasis management. The objective of this study was to review its adoption and use as a clinically effective laser lithotrite.

Femtosecond thulium fiber laser utilizing a gain-switched laser diode [PDF]
Optics LettersWe present an ultrafast thulium fiber laser based on nonlinear pulse compression of a gain-switched laser diode operating at 1.87 µm. Seeded by a 40-ps gain-switched laser diode (GSLD), thulium-doped fiber amplifiers (TDFA) are used to increase the pulse peak power, and a normal-dispersion highly nonlinear fiber (HNF) is employed to generate a positive

Dual-wavelength Q-switched thulium doped fiber laser with TiO2 film saturable absorber
, 2018 We report a dual-wavelength Q-switched Thulium doped fiber laser based on a Titanium dioxide (TiO2) saturable absorber. The TiO2 was embedded in polyvinyl alcohol (PVA) film, which was then sandwiched in between two fiber ferrules in the cavity. By using
