A dot pattern of a refractive-index change was formed by spot heating with laser-beam irradiation on sodium tellurite glasses. The 15Na2O.85TeO2 (mol. %) glass doped with 2 mol. % of CoO was irradiated by a green light-beam spot (532 nm) approximately 800 microm in diameter from the ...
We introduce the refractiveindex.info database, a comprehensive open-source repository containing optical constants for a wide array of materials, and describe in detail the underlying dataset. This collection, derived from a meticulous compilation of data sourced from peer-reviewed publications, manufact...
6.2.1 Refractive Index The refractive index, n, of a material is defined as the ratio of the velocity of light in a vacuum relative to the velocity of light passing through that material. The refractive index in a vacuum is defined as 1, and the refractive index of air at 20 °C and...
