Abstract
The time-resolved mode-mismatched thermal lens technique has been used to determine the thermal diffusivity, D, temperature behavior of a fluoride glass (ZBLAN) from 25 to 315 degree(s)C. We observed an abrupt decrease on D with minimum at 298 degree(s)C which coincides with the glass transition temperature Tg value measured by DSC. These measurements indicate that the thermal conductivity, K, decrease by factor approximately 8.
