“…Moreover,~3 µm lasers can be used as the pumping source of optical parametric oscillation (OPO) [11]. Two approaches have been widely investigated: bulk material lasers and fiber-based lasers [12]. Among low-phonon glasses, the fluoroindate glasses are very useful MID-IR photonic materials.…”

This work reports on the fabrication and analysis of near-infrared and mid-infrared luminescence spectra and their decays in fluoroindate glasses co-doped with Yb3+/Ho3+. The attention has been paid to the analysis of the Yb3+→ Ho3+ energy transfer processed ions in fluoroindate glasses pumped by 976 nm laser diode. The most effective sensitization for 2 μm luminescence has been obtained in glass co-doped with 0.8YbF3/1.6HoF3. Further study in the mid-infrared spectral range (2.85 μm) showed that the maximum emission intensity has been obtained in fluoroindate glass co-doped with 0.1YbF3/1.4HoF3. The obtained efficiency of Yb3+→ Ho3+ energy transfer was calculated to be up to 61% (0.8YbF3/1.6HoF3), which confirms the possibility of obtaining an efficient glass or glass fiber infrared source for a MID-infrared (MID-IR) sensing application.

This study reports a mid-infrared Ho 3+ :BaY 2 F 8 laser directly pumped by laser diodes (LDs). A finite element method (FEM) was used to calculate the temperature and thermal stress distributions inside the Ho 3+ :BYF crystal. The damage conditions have been evaluated on the basis of the experimental results. Using 889 nm LDs with the repetition frequency and pulse duration of 13 Hz and 100 μs, respectively, an output pulse energy of 1.05 mJ at 3.9 μm for the pump pulse energy of 336.8 mJ was achieved. The study might be useful for constructing a compact and robust mid-infrared laser.

“…As an example, dysprosium and holmium ions allow emission at wavelengths beyond 3 [12,25]. Recently, holmium-doped fluoroindate fibers have been characterized [25][26][27][28][29] and CW lasers emitting at = 2.875 [30] and = 3.92 [31,32], pumped at = 1120 and = 888 respectively, have been demonstrated. For that pertaining the pulsed laser operation, emissions at the wavelength = 2.106 [33] and in the = 2.95 − 3.015 range [34] have been obtained.…”

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 =. . The laser, pumped at = , is modeled by a sixlevel system, by taking into account experimental spectroscopic parameters, to identify a feasible laser configuration. An output signal peak power of about =. with a full width at half maximum (FWHM) pulse duration less than = and pulse energy =. is predicted, by considering an input peak power of = , and pump repetition rate of = , by employing a 8 cm-long fluoroindate fiber with holmium concentration =. 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. Index Terms-electromagnetic design, fiber laser, fluoroindate glass, gain switching, holmium, middle infrared. I. INTRODUCTION ULSED lasers in the middle-infrared (Mid-IR) wavelength range find wide application in several fields, including freespace communications, remote sensing, biological sensing, medical diagnostics and surgery, agri-food and environmental monitoring since many chemical molecules show Mid-IR absorption [1-8]. Those potential applications have attracted great research interest towards fiber lasers emitting at wavelengths beyond 3. During the recent years, a huge quantity of fiber lasers has been constructed by using different host materials which include silica, germanate, tellurite, ZBLAN or fluoroindate glasses. These glasses have been doped/co-doped with different rare-earth ions such as erbium, ytterbium, dysprosium, thulium, holmium, and praseodymium, to obtain emission at different wavelengths [9-13]. Great research interest was focused on Er 3+-doped fluoride fiber, since emission at about = 2.8 and = 3.5 allowed to obtain intriguing laser in
