Journal of Optics A: Pure and Applied Optics, 1999•iopscience.iop.orgWe propose a new approach that combines original techniques to achieve a very efficient
laser beam homogenizer and shaper. The three retained concepts are microlens array,
random phase plate and diffractive optical elements. The performance of usual
homogenizers are improved in terms of efficiency, homogenization and shaping abilities. We
report on the theory and the development of such diffractive beamshaper homogenizers.
Finally, an application concerning laser to fibre coupling is described.

Abstract
We propose a new approach that combines original techniques to achieve a very efficient laser beam homogenizer and shaper. The three retained concepts are microlens array, random phase plate and diffractive optical elements. The performance of usual homogenizers are improved in terms of efficiency, homogenization and shaping abilities. We report on the theory and the development of such diffractive beamshaper homogenizers. Finally, an application concerning laser to fibre coupling is described.
