Contribution of theoretical chemistry to the investigation of optical nonlinearities in glasses

The origin of optical non-linear response has been investigated in titaniumand niobium borophosphate glasses and in tellurite glasses. Correlations between the local structureof polarizable entities within the glasses and their optical activities have been tentativelyestablished through a semi-empirical model and ab-initio calculations.
