The effects connected with the laser modes' variations at volume hologram recording and reconstruction are studied. The results of the theoretical analysis for the reconstructing wave are compared with experimentally obtained data. Photorefractive Fe doped LiNbO$-3$/ crystals are used as the recording media for volume holographic storage. Laser modes of different indices were applied at hologram reconstruction, and methods of the diffracted beam intensity enhancement are discussed.
