Paper Abstract

Optical and photostability measurements have been made on nonlinear optical films containing amorphous polycarbonate and an organic chromophore that has a high 2nd order nonlinear optical figure of merit. We show that the decrease in the photodegradation quantum efficiency with increasing optical intensity can be modelled in terms of oxygen depletion by oxygen-mediated chomophore photodegradation. The addition of a known singlet oxygen quencher, beta carotene, leads to a 1100% decrease in the photodegradation quantum efficiency.
