Abstract

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.
控制能量传递的可控全息光栅的制作
本文从理论和实验两方面研究了可控衍射光栅上光束管理的特点。在波传播的方向上,沿样品厚度方向的相位对比是不均匀的。同时还考虑了光栅与折射率光栅之间空间位移的影响。移频光栅自衍射的自洽问题使得光强分布沿试样厚度呈孤子状包络。我们表明,由于光栅上的衍射,弱光束的能量传递增加,光栅具有从自洽任务获得的sech函数形式的相对比轮廓。
