Narrow-band holographic interference LiNbO3-based filters

New experimental data on antiparallel-beam holograms recorded in LiNbO3, te mperature fixation of the recorded holographic gratings, and the spectral c haracteristic of a narrow-band (0.01 nm) interference filter are reported. The effects of asymmetry in the diffraction efficiency and the emergence of satellites in the transmission spectrum of the filter are observed. These effects are explained using the birefringence properties of the crystal and the ability of holograms to transfer power between the beams in the course of recording.
