Abstract

The effect of the linear and non-linear imaginary parts of polarizability or connected with them linear a and two-photon b absorption on transmission and optical damage threshold obtained at the different technology conditions 2 3 AsS glasses were investigated. It was established, that with increasing of the melting temperature i and velocity of cooling Vi values the forbidden gap width of glasses increase at the decreasing of their density, refractive indices (from 2.71 to 2.48) and two-photon absorption coefficient (from 0.37 to 0,15 cm/MW), that is accompanied by the appropriate increasing of optical damage threshold d...
