Abstract

The properties of a volume recording of an intensity travelling wave, formed as a result of interference of two waves of different frequencies, are considered. It is shown that, when such a travelling wave is recorded in a medium capable of the stimulated Raman scattering at a resonance frequency equal exactly to the frequency difference of the interfering waves, so-called sfift volume dynamic hologram is obtained. Such a hologram provides the effective energy transfer from one of the interfering waves into another, because the shift is equal to a quarter of a period in this case. The simple interpretation of the process of the energy transfer in a shift hologram is presented.
