Elimination of Oxygen Inhibition in Photopolymer Systems Used as Holographic Recording Materials

Abstract One of the problems involved in increasing photopolymer sensitivity, is oxygen inhibition. In this paper we present a photochemical process in which a two dye-sensitizer in the photoinitiator system leads to the suppression of the inhibiting effect of the oxygen. Additionally, the photochemical system presents the possibility of a panchromatic system with light sensitivity in the green and red lines. Diffraction efficiencies of 40% in the 514 and 633 nm lines are obtained with a sensitivity of less than 10 mJ cm−2.
