Abstract
A gain-switched pulsed laser based on a commercial, heavily holmium-doped fluoroindate glass fiber, is designed to emit in the middle-infrared range, at the wavelength
$\boldsymbol{\lambda } = 3.92\ {\boldsymbol{\mu } \bf{ m}}$
. The laser, pumped at
${\boldsymbol{\lambda }} = 888{\bf{\ nm}}$
, is modeled by a six-level system, by taking into account experimental spectroscopic parameters, to identify a feasible laser configuration. An output signal peak power of about
${\boldsymbol{P}}_{\boldsymbol{s}}^{{\boldsymbol{peak}}} = 14.62{\bf{\ W}}$
with a full width at half maximum (FWHM) pulse duration less than
${{\boldsymbol{\tau }}_{\boldsymbol{s}}} = 73\ {\boldsymbol{ns}}$
and pulse energy
${{\boldsymbol{E}}_{\boldsymbol{s}}} = 1.214\ {\boldsymbol{\mu } \bf {J}}$
is predicted, by considering an input peak power of
${\boldsymbol{P}}_{\boldsymbol{p}}^{{\boldsymbol{peak}}} = 10{\bf{\ W}}$
, and pump repetition rate of
${\boldsymbol{f}} = 100{\bf{\ kHz}}$
, by employing a 8 cm-long fluoroindate fiber with holmium concentration
${{\boldsymbol{N}}_{{\boldsymbol{Ho}}}} = 100\ 000{\bf{\ ppm}}$
. The obtained result encourages the construction of a pulsed laser based on commercially available optical fiber, for applications in different fields as sensing and biomedicine.
