Abstract: A method of forming non-Gaussian light beams with a uniform spatial intensity distribution is studied. It uses a generalised confocal laser cavity, with one of the mirrors made in the form of a mask with discretely arranged phase-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.
