Many experiments and industrial applications require a laser beam irradiance that is nominally constant over a specified area. Such applications include surface treatment, drilling and welding, as well as the processing and recording of optical information. So in many case it is desirable that the beam-shaping operation conserves energy. For a beam with Gaussian profile, it is possible to map the beam into a uniform intensity profile with steep skirt.
