Theoretical Analysis of Gaussian Beam Diffraction on the Phase Step Structure

Cover Page

Abstract


The paper analyzes the interaction of a Gaussian beam with a phase step structure (PSS). The shape of the spatial spectrum at the output of such a scheme is examined. The most detailed description was done for the case when the size of the PSS phase difference is 180 degrees. The effects that occur at the displacement of SPS in the plane perpendicular to the direction of incidence of the laser beam were considered. Discussions for the possible practical application of the scheme were carried out.
