Abstract
One of the efficiency-limiting factors of optical devices used at high intensities is photo damage to the optical materials. In devices that use organic dyes, photo damage causes irreversible damage to the chromophores, deteriorating efficiency, and eventually causes failure. Our present work focuses on monitoring degradation and recovery of anthraquinone dye doped PMMA thin films with a digital imaging apparatus, with the goal of understanding the mechanisms. Our results suggest the possibility of making optical components more resistant to photodamage, and capable of self recovery, removing the necessity to constantly replace components damaged by high intensity light.
