| Abstract: | The holographic characteristics of a novel greenlight sensitive photopolymer with high diffraction efficiency and refractive index modulation are discussed. The influence of the exposure, recording intensity, intensity ratio of reference and object wave on the diffration efficiency are studied. The shortage to the high density recording of over exposure is displayed. |
