Abstract:
An investigation on the panchromaticity of a silver-doped poly(vinyl alcohol)/acrylamide photopolymer
system is presented in this paper. Frequency-doubled Nd:YAG (532 nm) and Arþ (488 nm) lasers were
used for the characterization of the films. Previous studies using an He–Ne laser (632:8 nm) showed that
plane-wave transmission grating with a high diffraction efficiency of 75% could be stored in the optimized
film. From the present study, it was noted that transmission gratings with 70% diffraction efficiency
could be recorded using Arþ and Nd:YAG lasers, thereby elucidating the possibility of using the developed
photopolymer system as a competent panchromatic recording medium
