High-power all-fiberized thulium-doped fiber MOPA
Laser Physics Letters, 2013We demonstrate a high-power all-fiberized thulium-doped fiber laser in a master oscillator power amplifier (MOPA) architecture giving output powers up to 100.4 W. A large-mode-area double-clad active fiber is employed as the gain medium. The laser is pumped by pigtailed laser diodes (LD) with a central wavelength of 792 nm.

Spectral hole burning measurement thulium-doped fiber amplifiers
Optics Letters, 2002An accurate technique was implemented to measure spectral hole burning in rare-earth amplifiers at room temperature, showing that thulium-doped fiber amplifiers exhibit hole depths four times lower than those of C -band erbium-doped fiber amplifiers.

Q-switched thulium-doped photonic crystal fiber laser
Optics Letters, 2012We report a novel, Tm-doped photonic crystal fiber (PCF) actively Q-switched oscillator that provides ~8.9 kW peak power with 435 µJ, 49 ns pulses at 10 kHz repetition rate at 2 μm wavelength. This fiber has a mode-field area >1000 μm2, the largest of any flexible PCF providing diffraction-limited beam quality to the best of our knowledge.

S-band amplification in a thulium doped silicate fiber
Optical Fiber Communication Conference and International Conference on Quantum Information, 2001We demonstrate significant gain over 1470-1540 nm in a thulium doped silica fiber amplifier. The fiber is compatible with standard fabrication techniques, and can be fusion spliced to standard telecommunications fibers. we report the first demonstration of an S-band thulium doped fiber amplifier (TDFA) using a true silicate fiber host which is readily ...

Mode-locked tunable thulium-doped fiber laser
SPIE Proceedings, 2017We report on an all-fiber, actively mode-locked, tunable, Thulium-doped, fiber laser based on a 20-GHz bandwidth electro-optic intensity modulator (EOM) and a voltage driven 2-μm, intra-cavity, fiber-coupled, Fabry-Perot tunable filter (FFP-TF). The repetition rate of output pulses was 47 MHz and the shortest measured output pulse width was 445 ps.

Thulium-doped fiber sources for novel applications [PDF]
, 2015 Very recently, the 2µm wavelength region is attracting growing attention as a potential new transmission window for optical communications to accommodate the everincreasing internet traffic. This is underpinned by the emerging technology of hollowcore photonic bandgap fibers (HC-PBGFs), which holds great promise as a transmission medium with predicted ...
