摘要：
Methods and apparatus for treatment, such as skin rejuvenation treatment, using non-uniform laser radiation. An output beam from a laser source is coupled into an optical system that modifies the beam to provide a large-diameter beam having a non-uniform energy profile, comprised of a plurality of high-intensity zones surrounded by lower-intensity zones within the treatment beam. A large area of tissue, preferably 7-10 mm in diameter, can be treated simultaneously, while minimizing the risk of burning or other damage to the skin.
