Optical and structural properties of Sb$_2$S$_3$/MgF$_2$ multilayers for laser applications

Abstract

Multilayers of MgF2 and Sb2S3 have been obtained by physical vapour deposition on glass substrates. Changes in the optical and structural properties have been studied as a function of annealing temperature and the number of layers. A drastic variation in optical transmission, microstrain and grain size is observed at a temperature near 225°C. A comparison of the material properties of multilayers and a monolayer is carried out.
