Chapter 2: Laser Irradiation Effect on Optical Properties of Chalcogenide Glasses
The aim of the present work is to prepare amorphous Se-Te based glassy alloy with different additive by melt quenching technique and to investigate the laser irradiation effect on optical properties of prepared glassy alloys. To investigate the effect of laser irradiation on optical properties of prepared glassy alloys, thin films of each composition have been prepared by thermal evaporation technique. Prepared amorphous thin films have been irradiated with a pulsed Transverse Electrical Excitation at Atmospheric pressure (TEA) Nitrogen Laser and characterized before and after different time of irradiation by using UV/Visible Spectrophotometer.
