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

Applied 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 ...

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 ...

Gain dynamics in thulium-doped fiber amplifiers

Optics 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 ...
