Laser-induced effects on dielectric relaxation of multi-component Se76Te20Sn2Cd2 chalcogenide glass

In present 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 dielectric properties to check the candidature of this material for possible application in optoelectronics. The temperature and frequency dependence of dielectric constant (ε′) and dielectric loss (ε″) of unexposed and laser-exposed exposed samples are studied over audible frequency range (1-10 kHz). The comprehensive investigation proves the applicability of the Guintini's theory of dielectric dispersion for the present dielectric loss data.
