Abstract
The experimental evidence of slow absorption grating formation in a photorefractive BTO crystal is presented. The absorption grating is recorded together with the usual photorefractive one during the long exposure time in a self-stabilized holographic setup. Due to the different nature of both gratings (the amplitude grating is assumed to be isotropic) the analysis of the polarization state of the diffracted beam allows the authors to prove the existence of an absorption grating. The strong two-wave mixing influence on the hologram readout process is demonstrated.
