Abstract

Some years ago we had elaborated the new photopolymer composite to record in real time (or quasi real time) the various volume phase transmission-transmission holographical devices: gratings, lenses, beam-multiplicators, narrow-band filters. The nonreversible real-time recording on the photopolymers was based on the chain radical polymerication reaction and resulted in phase transition from liquid monomer/olygomer mixture to a solid with spatially modulated surface and volume. Unfortunately, in most cases the polymerizing recording is followed simultaneously by the shrinkage and the variation of the bulk index reaction. Unlike the transmission holograms the recording of the reflection holograms in real-time mode becomes impossible until these effects can be limited or aborted. The present paper contains the corresponding results of investigation of the photopolymer recording real-time modes of the reflection holographic gratings: (1) photopolymer composites with the smallest variation of the bulk refraction index during the real-time recording, (2) effect of a shrinkage on the diffraction efficiency of gratings, (3) limitations of the post-polymerized amplification of a holographic recording for the reflection gratings, and (4) the capillary-induced filling of the phase plates of the reflective hologram gratings as the tentative explanation of the positive results.
