A Passively Q-Switched Holmium-Doped Fiber Laser with Graphene Oxide at 2058 nm
Applied Sciences, 2021 This study reports a Q-switching-based, 2058-nm holmium (Ho) fiber laser incorporating a saturable absorber (SA) based on graphene oxide (GO). The SA was prepared with a side-polished fiber, while GO particles were deposited onto the fiber-polished ...

High power tandem-pumped thulium-doped fiber laser
Optics Express, 2015 We propose a cascaded tandem pumping technique and show its high power and high efficient operation in the 2-μm wavelength region, opening up a new way to scale the output power of the 2-μm fiber laser to new levels (e.g. 10 kW). Using a 1942 nm Tm(3+) fiber laser as the pump source with the co- (counter-) propagating configuration, the 2020 nm Tm(3 ...

Tunable 30W all-fiber laser emitting around 1850 nm [PDF]
EPJ Web of ConferencesWe have demonstrated a tunable polarization maintaining thulium-doped fiber laser spanning the 1830nm-1880nm range with a fiber-coupled output power as high as 30W CW. The high- power booster stage is made using double clad fibers pumped with 793nm laser

Generation of Q-switched thulium-doped fiber laser (TDFL) using differentsaturable absorbers [PDF]
, 2016 A Q-switched Thulium-doped Fiber Laser (TDFL) operating at approximately 2 µm wavelength is successfully generated by using four different saturable absorbers (SAs) which are nitrogen-doped graphene in PVA (NG:PVA), nitrogen-doped graphene in PEO (NG:PEO)

Thulium-doped silica-based optical fibers for cladding-pumped fiber amplifiers [PDF]
Optical Materials, 2007 We present preparation and spectroscopic characterization of the Tm-doped fibers with enhanced 3H4 fluorescence lifetime thanks to codoping with alumina. With the alumina content of 10 mol %, the fluorescence lifetime of 58 μs was achieved. Using experimentally obtained fiber characteristics, we used numerical simulations to study and optimize for the ...
