Fabrication of controllable holographic gratings to manage the energy transfer

The peculiarities of managements of optical beams on controlled diffraction gratings are investigating both theoretically and experimentally. The gratings are distinguished by non-uniform phase contrast along a thickness of a sample in the direction of wave propagation. The manipulation of a space shift between the light grating and the refractive-index grating is taken into account as well. The self-consistent problem of the self-diffraction of waves from shifter gratings gives that the intensity profile gets a soliton-like envelope along the thickness of the sample. We show that energy transfer is increased for a weak beam due to diffraction on a grating, which has a profile of a phase contrast in a form of a sech-function obtained from a self-consistent task.
