Broadband thulium-doped fiber ASE source
Optics Letters, 2020We report on a flat and broadband thulium-doped amplified spontaneous emission (ASE) fiber source working around 1.85 µm in the eye-safe spectral region. Core-pumped thulium fibers were prepared in-house using the modified chemical vapor deposition method. The amplified spontaneous emission source in a backward direction with respect to the pump and in

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.

Thulium-Doped Tellurite Fiber Amplifier
IEEE Photonics Technology Letters, 2004Gain in the S-band is demonstrated in a thulium-doped tellurite fiber amplifier using dual pump and bidirectional pumping schemes. Two pump schemes were employed: 795/1064 and 1047/1550 nm. The gain profile is broader than achieved in a fluoride fiber and overlaps with the C-band of the erbium-doped fiber amplifier. We reach a fiber-to-fiber gain of 11

Photoinduced absorption in thulium-doped ZBLAN fibers
Optics Letters, 1995We report on the observation of photoinduced absorption in four different thulium-doped ZBLAN fibers exposed to 1.12-μm light. The darkening rate is shown to follow a fourth-power dependence on the pumping intensity and a strong dependence on the Tm3+ concentration.

Dispersion-managed thulium-doped fiber Mamyshev oscillator
Fiber Lasers XVIII: Technology and Systems, 2021The principle of a Mamyshev oscillator depends on alternating spectral filtering between sections of spectral broadening by self-phase modulation. In the 2 µm wavelength range, this concept faces the difficulty that standard fibers are anomalous dispersive which limits the possible pulse energy to the pJ-regime without proper dispersion management.

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.

Thulium-doped optical fibers for fiber lasers
Photonics, Devices, and Systems VII, 2017We present preparation and characterization of thulium-doped silica-based optical fibers for fiber lasers. The fibers were prepared by modified chemical vapor deposition process and doped with alumina and thulium ions. Alumina co-doping was achieved through two different methods – solution doping and nanoparticle doping method.

Tunable thulium-doped all-fiber laser
IEEE Photonics Technology Letters, 1998We demonstrate a tunable thulium-doped fiber ring laser wherein a single fused coupler acts simultaneously as the wavelength-division multiplexing for pump radiation, a lasing wavelength selective element, and output mirror. Temperature tuning of up to 2 nm//spl deg/C over a range of 40 nm and polarization tuning of over 100 nm within the spectral ...
