Paper Abstract

We present an optical system which simultaneously makes homogeneous the spatial energy distribution and varies the spot size of any light beam, including beams having asymmetric intensity spikes, without replacement of lenses and without changing the total length of the optical system. This homogenizer technology (patent pending) includes a software to design the optimum optical system to achieve the wished output beam performance, as well as to know how the beam shape changes when changing the position of each optical element. In this paper, we illustrate the principle of the new homogenizer, the design software performance and the experimental results achieved applying our technology to a large volume excimer laser.
