Dispersion-managed Monolithic All Polarization-Maintaining Ultrafast Thulium-doped Fiber Oscillator [PDF]

open access: yesEPJ Web of Conferences, 2022
We report on our first results of a dispersion-managed monolithic polarization-maintaining ultrafast Thulium-doped fiber oscillator. The design incorporates only commercially available polarization-maintaining components and emits linearly polarized ...

110 W All Fiber Actively Q-Switched Thulium-Doped Fiber Laser

open access: yesIEEE Photonics Journal, 2015
We report a 100-W-level, repetition rate and pulsewidth tunable, all-fiber, thulium-doped master oscillator power amplifier system. The master oscillator was actively Q-switched by a fiber-coupled acousto-optic modulator.

A Passively Q-Switched Holmium-Doped Fiber Laser with Graphene Oxide at 2058 nm

open access: yesApplied 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 ...

Tunable 30W all-fiber laser emitting around 1850 nm [PDF]

open access: yesEPJ Web of Conferences
We 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

Ytterbium-Codoping in Thulium Doped Silica Fiber

open access: yesPIERS Online, 2005
A novel ytterbium-thulium codoping scheme is presented taking advantage of the fact that ytterbium codoping in thulium could facilitate population inversion between the relevant energy levels, through a cross energy transfer process between Tm 3+ and Yb 3+ .A set of nonlinear coupled ODEs which govern the dynamics of optical amplification in the ...

Kerr nonlinearity of Thulium-doped fiber near 2 μm

open access: yesCLEO: 2015, 2015
The nonlinear coefficient and group velocity dispersion of a thulium-doped fiber near 2μm are evaluated via four-wave mixing. Nonlinearity of thulium-doped fiber can be used for the design of doped-fiber lasers in this spectral region.

Emission Wavelength Limits of a Continuous-Wave Thulium-Doped Fiber Laser Source Operating at 1.94 µm, 2.09 µm or 2.12 µm

open access: yesPhotonics
We present a thulium-doped single-oscillator monolithic fiber laser emitting successively at three wavelengths, especially at unusual long wavelengths as 2.09 µm and even at 2.12 µm.

Gain dynamics in thulium-doped fiber amplifiers

open access: yesOptics Express
Understanding the gain dynamics of amplification in rare-earth-doped silica glass fibers is crucial for developing sophisticated low-noise amplifiers and frequency combs. Recent and ongoing research efforts in these areas have specifically targeted the spectral region around 2 µm and the use of thulium-doped silica glass fibers as a broadband, power ...
