Abstract

In this work we demonstrate wavefront complex modulation of semiconductor light sources via digital micromirror device (DMD). Proposed holographic configuration allows to correct the aberrations caused by the imperfections of the DMD and the optical elements. We consider the blazing effect of the DMD surface and configured the optimal condition of the optical setup for certain DMD and the wavelength of the radiation source. The technique was approved with the experiment of obtaining different kinds of wavefront distributions from the semiconductor laser with high M2 factor.
