Influence of the Laser on the Mechanical Properties of GeSe9 Chalcogenide Glasses

Photoinduced changes in the mechanical properties of Ge-Se chalcogenide glasses produced by sub-band gap energy are studied by microindentation. The results show that the irradiation leads to an increase of the mechanical properties exactly module of Young and the hardness with a decrease of the viscosity in the case of the low intensities laser and a decrease of the mechanical properties with an increase of the viscosity in the case of the high intensities of irradiation.
