Journal ArticleDOI
Energy transfer between Er 3 + and Tm 3 + ions in a barium fluoride – thorium fluoride glass
TL;DR: In this paper, the up-conversion of infrared radiation into green, red, and 805-nm fluorescence has been studied for the ionization of fluorine glass over a wide temperature range and several dopant concentrations.
Journal ArticleDOI
Spectroscopic properties and laser emission of Tm doped ZBLAN glass at 1.8 μm
TL;DR: In this article, a Tm doped ZBLAN glass is investigated to obtain a laser emission near 1.8 μm instead of classical crystalline host materials, and a brief description of the basic optical properties of this glass is presented.
Journal ArticleDOI
Time-resolved fluorescence-line narrowing and energy-transfer studies in a Eu 3 + -doped fluorophosphate glass
TL;DR: In this article, the optical properties of fluorophosphate glasses of composition were investigated in the 4.2-300 K temperature range by using optical absorption spectroscopy and time-resolved resonant laser-induced fluorescence line narrowing.
Journal ArticleDOI
Anti-Stokes laser-induced internal cooling of Yb 3+ -doped glasses
TL;DR: In this paper, an anti-Stokes cooling between room temperature and 77 K in a fluorochloride glass (CNBZn) and a fluoride glass (BIG) doped with 1 mol % of YbF 3, was demonstrated by using collinear photothermal deflection and conventional laser excitation spectroscopies under high photon irradiances.
Journal ArticleDOI
Fluorescence mechanisms in Tm 3+ singly doped and Tm 3+ , Ho 3+ doubly doped indium-based fluoride glasses
TL;DR: The regime of diffusion among the Tm-doped and (Tm,Ho)-doped indium-based fluoride glasses ions is clearly established and the cross-relaxation of the lowest excited states has been proved and its efficiency calculated.
