Thulium-Doped Silica Fibers with Enhanced Fluorescence Lifetime and Their Application in Ultrafast Fiber Lasers

Fibers, 2018
In this work we report on the thulium-doped silica-based optical fibers with increased fluorescence lifetime of the 3F4 level thanks to the modification of the local environment of thulium ions by high content of alumina.

Repetition-Rate-Switchable and Self-Mode-Locked Pulses Generation From a Gain-Switched Thulium-Doped Fiber Laser and Their Amplification Properties

IEEE Photonics Journal, 2017
We report on repetition-rate-switchable and self-mode-locked pulses generation from a gain-switched thulium-doped fiber laser. Stable pulse trains were gain-switched by a home-made, pulsed Erbium/Ytterbium codoped fiber amplifier.

Ytterbium-Codoping in Thulium Doped Silica Fiber

PIERS 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 ...
