Paper Abstract

In this paper, principle and design of high spatial frequency rectangular phase optic grating used as high- efficiency, micro energy beam-splitter are discussed. By using Fourier integration, lightwave electromagnetic vector diffraction model for high spatial frequency grating is made, and with the help of computer, grating structure parameters' effect upon beam-slitting efficiency is simulated. In order to evaluate the design effect of grating, an evaluation function is introduced. Finally, the design of grating laser beam-slitting system is optimized.
