Self-recording phenomenon in the process of reconstruction from a highly efficient dynamic hologram on azo-dye-colored material with powerful Weigert's effect.
The dynamic process of highly efficient holographic recording of two orthogonally circularly polarized plane light waves on the azo-dye-colored gelatin with powerful Weigert's effect is investigated. The investigation has shown that at some ratios of the intensities of the recording waves the self-recording phenomenon during the reconstruction process by the same actinic light (lambda=488.0 nm) is observed, and the diffractive efficiency for the probe light (lambda=632.8 nm) of an already fully recorded hologram increases again almost instantly after blocking one of the recording beams of low intensity. The maximum diffractive efficiency reaches 40%-45% in this case.
