“…4 I 11/2 transition. Several results have been reported on the luminescent properties of Nd 3+ ions in a variety of glass matrices which include silicates [14], borates [6], tellurites [15] and chalocogenides [16]. Thus, the luminescent properties of the Nd 3+ ions are considerably modified by suitably selecting the network of the forming and the modifying cations.…”

a b s t r a c tA study of the optical properties of Nd 3+ ion in TeO 2 -PbF 2 -AlF 3 glasses has been carried out for different Nd 3+ concentrations. Based on the Judd-Ofelt theory, intensity parameters and radiative properties were determined from the absorption spectra. Focusing on the suitability of this host for laser applications, the spectroscopic quality factor v was obtained with a value of 1.07, a value of the order of other compositions proposed as laser hosts. For the most intense emission corresponding with the 4 F 3/2 ? 4 I 11/2 transition (1.06 lm), the absorption and emission and have been calculated with values of 1.20 Â 10 À20 cm 2 , 2.08 Â 10 À20 cm 2 . A positive value for the gain cross-sections has been found for a population inversion factor c of 0.4 in the spectral range from 1060 to 1110 nm. All these results suggest the potentially use of this system as a laser host.

“…Over a number of years, significant progress towards the development of lanthanide ion doped MIR fibre lasers with lasing characteristics at least comparable to those offered by OPOs or QCLs has been made (Nostrand 1999;Shaw et al 2001;Sanghera et al 2009). One of the main impediments to the development of efficient lanthanide ion doped low phonon energy glass fibre lasers for the MIR wavelength range is that, so far, an efficient 3 or 4 level system for this wavelength range has not been identified.…”

Modelling of a simple Dy3+ doped chalcogenide glass fibre laser for mid-infrared light generation

et al. 2010

A simple Dy 3+ -doped chalcogenide glass fibre laser design for mid-infrared light generation is studied using a one dimensional rate equation model. The fibre laser design employs the concept of cascade lasing. The results obtained demonstrate that efficient cascade lasing may be achieved in practice without the need for fibre grating fabrication, as a sufficient level of feedback for laser action is provided by Fresnel light reflection at chalcogenide glass fibre-air interfaces. Further enhancement of the laser efficiency can be achieved by terminating one of the fibre ends with a mirror. A numerical analysis of the effect of the Dy 3+ doping concentration and fibre loss on the laser operation shows that with 5 W of pump power, at 1.71 µm wavelength, output powers above 100 mW at ∼ 4.5 µm wavelength can be achieved with Dy 3+ ion concentrations as low as 3 × 10 19 cm −3 , when fibre loss is of the order 1dB/m.

Glassy Materials and Light: Part 1

publicado na web em 05/02/2016 GLASSY MATERIALS AND LIGHT: PART 1. 2015 is the Year of Light, according to UNESCO. Chemistry has a close relationship with light and one of the materials that allows such synergy is glass. Depending on the chemical composition of the glass, it is possible to achieve technological applications for the whole range of wavelengths extending from the region of the microwave to gamma rays. This diversity of applications opens a large range of research where chemistry, as a central science, overlaps the fields of physics, engineering, medicine, etc., generating a huge amount of knowledge and technological products used for humanity. This review article aimed at discussing some families of glasses, illustrating some applications. Due to the extension of the theme, and all points raised, we thought it would be good to divide the article into two parts. In the first part we focus on the properties of heavy metal oxide glasses, fluoride glasses and chalcogenide glasses. In the second part we emphasize the properties of glassy thin films prepared by sol-gel methodology and some applications, of both glasses as the films in photonics, and more attention was given to the nonlinear properties and uses of photonic fibers.
