Abstract

A new photopolymer has been developed as a material candidate for high-density holographic data storage applications. Holographic gratings have been recorded on the polymer film using nanosecond laser pulses at 532 nm wavelength with diffraction efficiency measured up to 20%. Further studies have shown 14 line pairs/mm as the material resolution of our photopolymer films at the current development stage. Combined with the erasability results published earlier, the results presented in this paper suggest the possibility of both types of recording (rewritable with low-power CW laser recording and read-only with high-energy pulse laser recording) on this new photopolymer film.
