|Title:||Time-resolved Thermal Lens Measurements Of Thermo-optical Properties Of Fluoride Glasses|
|Abstract:||We present measurements of the temperature coefficient of optical path change, ds/dT, thermal diffusivity, D, and conductivity, K, using time-resolved mode-mismatched thermal lens method for fluoride (mol%) 53ZrF 4-4.5LaF 3-3.5AlF 3-29BaF 2-10NaF (ZBLAN), fluoroaluminate 20YF 3-40AlF 3-20CaF 2-20BaF 2 (YABC) and fluoroindates 20GaF 3-15InF 3-20CaF 2-15ZnF 2-30PbF 2 (PGIZCa), 6GaF 3-34InF 3-20SrF 2-16BaF 2-20ZnF 2-4NaF (ISZn), 2GdF 3-40InF 3-20SrF 2-16BaF 2-20ZnF 2-2%NaF (InSBZnGdN). All the samples were crystal free, as verified by X-ray diffraction (XRD), and were at least 3 mm thick. The ds/dT of our samples was negative, the thermal diffusivity, D, was found to vary between 2.5 and 3.3×10 -3 cm 2/s, and the thermal conductivity, K, varied between 7.4 and 10.3×10 -3 W/K cm.|
