the grating non-uniformity of the nonvolatile volume hologram recording in doubly doped linbo_3(ln) crystals mainly caused by strong ultraviolet (uv) absorption is studied in detail.
according to coupled wave theory, the volume hologram has a good property for light filtering and can be used as a kind of narrow-band filter.
根据耦合波理论,体积全息图有很好的滤光特性,可以作为一种窄带滤光片在实际中得到应用。
specifically disclosed is a photosensitive composition for volume hologram recording characterized by containing a photopolymerizable, volume-expandable compound and a photopolymerization initiator.
