Abstract

The laser-induced temperature rise in a dye/polymer system for optical storage was directly obtained by measuring the intensity ratio of the Raman scattered radiations (anti-Stokes to Stokes). The laser beam that writes is used to collect scattering data. Computer simulated laser-induced temperature distribution and its corresponding intensity ratio were used to extract the actual temperature information developed on the recording films. Experiments have been done at laser powers below and up to the point of threshold of marking.
