Intensification of a photorefractive response by an external ac field in the ferroelectric crystal Ba(2)NaNb(5)O(15).
Static photorefractive gratings are recorded by a running interference pattern in the ferroelectric crystal Ba(2)NaNb(5)O(15) with an externally applied ac field. Both two- and four-wave mixing based on this recording mechanism are investigated.
