Paper Abstract

A novel optical system is described which can be used to change the intensity profile of a laser beam without the increase in beam divergence which results from conventional techniques. The technique uses a telescope, the first lens of which is designed to introduce an amount of spherical aberration. This changes the intensity distribution of the beam in the focal region where a second lend is located. The second element removes the aberration and collimates the beam. Cylindrical lenses can be used to independently shape the intensity profile of the beam in the two azimuths.
