Monolithic thulium-doped fiber laser
Photonics, Devices, and Systems VII, 2017In this contribution we report and discuss the results of laser characterizations of experimental thulium-doped optical fibers. These active fibers were fabricated in house and were tested in two laser systems to verify their characteristics. The first one, a monolithic fiber laser, was of great interest to us due to its potentially lower overall ...

Thulium-doped ZBLAN fiber laser
SPIE Proceedings, 1999The thulium-doped ZBLAN fiber laser is emitting visible radiation through an upconversion process which allows for the generation of hundreds of milliwatts of output power at 480 nm. The main features of this laser are presented and analyzed on the basis of an equation rate analysis.

Photobleaching of thulium-doped ZBLAN fibers with visible light
Optics Letters, 1997Photobleaching of darkened thulium-doped ZBLAN fibers is observed after short exposure to visible light. The bleaching process is characterized by a stretched-exponential function of time with an exponent beta independent of both the bleaching intensity and the thulium concentration.

Lasing in thulium-doped polarizing photonic crystal fiber
Optics Letters, 2011We describe lasing of a thulium-doped polarizing photonic crystal fiber. A 4 m long fiber with 50 μm diameter core, 250 μm diameter cladding, and d/Λ ratio of 0.18 was pumped with a 793 nm diode and produced a polarized output with a polarization extinction ratio (PER) of 15 dB and an M(2) of

Bidirectional mode-locked thulium-doped fiber laser
Applied Optics, 2018We report a bidirectional mode-locked thulium-doped fiber laser. Mode-locking is enabled by the combination of semiconductor saturable absorption and nonlinear polarization rotation. Two stable mode-locked picosecond pulse trains in opposite directions are generated with a fundamental repetition rate of ∼16.57 MHz.

Progress in thulium doped fiber lasers and aplifiers
SPIE Proceedings, 2012We present results on the development of signal sources for the 2000 nm band. The ASE source is presented with a FWHM bandwidth of 70 nm and -20dB bandwidth of 229 nm with an integrated power of 7.5 mW. Narrow band lasers are presented made of a short piece of core-pumped thulium doped fiber and fiber Bragg gratings.

Thulium-doped fiber amplifier for the S-band
Proceedings of 2004 6th International Conference on Transparent Optical Networks (IEEE Cat. No.04EX804), 2004Two configurations of thulium-doped fiber amplifiers (TDFA) are presented and the performance of the amplifier in these configurations is discussed. The measurements are compared with a simulation using a self-written model and compared with results reported in the literature.

Fabrication of thulium-doped silica optical fiber
SPIE Proceedings, 1998In this article, we mainly describe the preparation of the silica optical fiber doped with rare earth ion Tm3+ by utilizing solution-doped technique, and the control of relevant parameters of the fiber. The control and the measurement method of dopantion concentration of Tm3+ have also been discussed.

Scaling Bottlenecks in Thulium-doped Fiber Lasers
Frontiers in Optics 2013, 2013Thulium offers novel applications at 2 μm, and with continued developments, peak and average powers will increase to that of rival rare-earth dopants. Limitations that impede growth are namely; nonlinearities, thermal management, and fiberized components.
