Determining Thermal Diffusivity and Thermo-Optic Coefficient of Europium Doped Tellurite Glass via x-scan Technique

Abstract

Thermal diffusivity and the thermo-optic coefficient, dn/dT, of europium doped tellurite glass were determined using the x-scan technique. We found that the thermal diffusivity is equal to 28x10-4 cm2/s and the average dn/dT =-5.28x10-6K-1.
