摘要：

Bragg-type polarization holograms were recorded in thick copolymer films with tolane and azobenzene moieties by interfering two orthogonal circularly polarized beams at 488 rim. Observation of the films with a polarizing optical microscope revealed that circular alignment of molecules was induced along a grating vector. An incident reading beam at 633 nm was efficiently diffracted, depending on its polarization state and incident direction.
