Abstract

We introduce a new optical system that is able to simultaneously make homogeneous the spatial energy distribution and vary the spot size of any light beam, including beams having strong local intensity fluctuations, without replacement of lenses and without changing the total length of the optical system. This homogeniser technology 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 present the design software and the experimental results achieved with our technology applied to a large volume excimer laser.
