Paper Abstract

Chalcogenide glasses are promising materials for production of different optical elements for integral and optoelectronics and laser devices. Generally it is due to the properties of the glasses that are transparent in visible and TR region of spectrum and posses different values of refractive indices and relatively low optical and acuostooptical losses. However, their relatively low damage threshold is the main restriction for their wide application. As it is known the damage threshold of a material is mostly defined by linear and nonlinear losses of laser radiation. The dependencies of linear losses coefficients α, two-photon absorption constant β, optical damage threshold Ip and pseudogap width Eo on component concentration x and average coordination number values r of ternary chalcogenide semiconductive glasses of Ge-As-S system have been experimentally determined by investigation of the high intensity dependencies of transmission of the ruby laser light emission.
