Abstract
The photorefractive volume holographic cylindrical lens taking on the wavelength conversion and the wave-front conversion synchronously was designed. Based on coupled wave theory, the wave-front conversion by local photorefractive volume holograms between cylindrical and plane waves which recoded at 632.8 nm and reconstructed at 800 nm is studied. The off-Bragg parameter at arbitrary point of the hologram in the reconstruction process is analyzed. The dependences of diffraction efficiency on the focal length of recording cylindrical wave and on the geometric size of the gratings on the hologram are discussed in detail. The amplitude distribution of the diffracted beam at the output boundary is also analyzed. Furthermore, the effect of selectivity of different on-Bragg reference point for recording hologram on the diffraction efficiency of the grating is discussed.
