title: Photorefractive response of bulk periodically poled LiNbO3:Y:Fe at high and low spatial frequencies
abstract: Polydomain periodically poled samples of iron-doped lithium niobate allow for phase grating recording with the diffraction efficiency close to that ensured by a single-domain sample with identical thickness. At the same time the optical damage induced by a finite transverse size light beam is considerably reduced in the periodically poled sample as compared with single-domain material.
