Reshaping collimated laser beams with Gaussian profile to uniform profiles.
A set of holographic filters was developed to convert the Gaussian intensity distribution of a collimated laser beam into a uniform one. The design and the fabricating method of the holographic filters are presented and experimental results are shown.
