A theoretical model to describe in-band pumped holmium doped silica fiber lasers is
presented. The model is established based upon theory and parameters obtained from …

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 …

In this Letter, a watt-level single-frequency fiber oscillator at 2050? nm was demonstrated for
the first time, to the best of our knowlegde, in a linear laser cavity with a piece of an un …

In this paper, we present the results of an experimental study on the characterization of
holmium-doped silica fiber. A standard acousto-optic modulator controls the output power of …

The presence of different modulators within a cavity often leads to increased losses and is
bound by temporal limitations. Therefore, it is reasonable to investigate alternative optical …

We report the first laser operation based on Ho^ 3+-doped LuLiF_4 single crystal, which is
directly pumped with 1.15-μm laser diode (LD). Based on the numerical model, it is found …

We report a holmium-doped all-fiber laser oscillating at~ 2.05 µm in continuous wave at
direct in-core pumping by a 1.125 µm laser diode. Two types of home-made holmium-doped …

We present a Ho 3+-doped YAG ceramic laser which is directly diode-pumped at~ 1.13 μm
for the first time. The Ho: YAG ceramic slab in this letter has a dimension of 4.2× 4.8× 22 mm …

Absorption of continuous wave and pulsed resonance radiation at a wavelength of 1.6 µm at
the upward transition from the excited state of holmium (Ho 3+) ions in silica-based fiber has …

In this report, a theoretical model of in-band pumped holmium-doped silica fiber amplifiers
(HDFAs) is presented. This model is developed to consider the influence of energy transfer …
