Abstract
A method of forming non-Gaussian light beams with a uniform spatial intensi ty distribution is studied. It uses a generalised confocal laser cavity, wi th one of the mirrors made in the form of a mask with discretely arranged p hase-shifting nonuniformities. The theoretical and experimental results of the study confirm the formation of such beams at the output of a CO2 laser with a nonuniform phase-stepped mirror.
