Abstract

Photopolymer is well-recognized as an ideal holographic recording medium, but there is holographic reciprocity law failure in pulse exposure. In this study, the holographic properties of the samples containing an acrylate dendritic monomer with high refractive index (DM-1, n=1.634) are investigated under a 532 nm single-pulse or multi-pulses exposure. The effects of pulse number, spatial frequency, thickness and exposure dosage on diffraction efficiency are discussed. The diffraction efficiency of recorded grating in a sample containing 4% DM-1 (0.5 mm thickness) reaches 77.2% under the 100 pulses exposure. Besides, a grating with diffraction efficiency of 1.35% and narrow selection angle of 0.11° can be recorded in this sample under a single-pulse exposure (8.7 mJ/cm² exposure dosage), indicating its’ potential in ultrafast holography.
