Abstract

In present novel work, we have synthesized a novel quaternary Se76Te20Sn2Cd2 glass in bulk form. Four laser light sources from UV-Vis-IR region have been used to investigate the laser-induced effects on the micro-hardness to check the candidature of this material for possible application in fiber optics. The micro-hardness of the quaternary Se76Te20Sn2Cd2 glass is increased appreciably after laser exposure. This result has been analyzed in terms of compactness. The enhancement in both micro-hardness and compactness is also explained by Raman spectroscopy.
