Abstract
The diffraction efficiency of volume gratings written by two-wave mixing in a cerium-doped potassium sodium strontium barium niobate (Ce:KNSBN) photor efractive crystal is studied. It is found that the diffraction efficiency s trongly depends on the polarization of writing beams and exhibits loop beha vior with respect to the fringe modulation. The fringe modulations before a nd behind the crystal are compared. Modified coupled-wave theory is used to fit the experimental data. This research presents data that are relevant t o the application of Ce:KNSBN crystals to holographic recording and optical information processing. (C) 1999 Optical Society of America.
