Abstract

The invention is directed to a mirror for changing the geometric shape of a light beam. A two-dimensional intensity distribution substantially independent of the mode structure can be generated by mounting a grating in the optical beam path of the laser beam. The intensity distribution is constant in one direction and, in a direction perpendicular thereto, the intensity can have any preselectable intensity distribution.
