Abstract
The phenomenon of energy transfer is considered by means of dynamic polarization holograms. The use of higheffective reversible polarization-sensitive media makes it possible to use beams with low intensities from CW lasers. For amplification of energy transfer, the additional mechanical shift of the medium was used such that the phase shift would be of optimal value π/2. The increase of the intensity of a weak beam up to 300% within the time of tens of milliseconds was obtained. This approach gives the possible to amplify coherent light beams by relatively simple way including the amplification of beams in communication systems.
