E. Fargin et al., CONTRIBUTION OF THEORETICAL CHEMISTRY TO THE INVESTIGATION OF OPTICALNON LINEARITIES IN GLASSES, Annales de chimie, 23(1-2), 1998, pp. 27-32
The origin of optical non-linear response has been investigated in tit
anium and niobium borophosphate glasses and in tellurite glasses. Corr
elations between the local structure of polarizable entities within th
e glasses and their optical activities have been tentatively establish
ed through a semi-empirical model and ab-initio calculations.
