Abstract
A device and a method for fractional skin treatment. The device employs two diffractive optical elements. One of the diffractive optical elements provides two coaxial laser beams and another diffractive optical element splits the two coaxial laser beams into a plurality of beamlets. A lens arranged to receive the plurality of the laser beams and to focus them in a skin treatment plane. The lens forms an image where each of the beamlets is imaged as a spot with a high intensity central area and a lower intensity area surrounding the central area.
