Abstract

The design of a set of filters reshaping collimated Gaussian beam into that with uniform intensity profile is based on the energy conservation law and the geometrical optics. The diffraction effects neglected during design process are evaluated using the boundary diffraction wave. An amplitude distribution at the plane of the second filter and the correction of the second filter, which collimates the beam after energy redistribution, are calculated.
