Abstract

The dependences of linear losses coefficient alpha and two- photon absorption constant beta on structure and concentration x or average coordination number r changes of Ge-As-S glasses along the As-GeS₂, As-Ge₂S₃, As₂S₃-GeS₂ and As₂S₃-Ge₂S₃ section have been experimentally studied. The critical values of x and r at which the alpha and beta reach their extrema were determined. The obtained results have been discussed in terms of phase and structure-topological transitions.
