Paper Abstract

A tapered lenslike system with gain or losses is proposed for converting a gaussian laser beam into an uniform beam. The best foci of the lenslike system are determined: Best Front Focal Distance (BFFD) and Best Back Focal Distance (BBFD). The results are applied to a medium with quadratic gain profile to achieve uniform illumination controlling the gain parameter.
