摘要：A method and apparatus are disclosed for laser treatment of surfaces, such astissue. In a preferred embodiment, the invention employs a unique reflective opticaldelivery system which produces an improved beam intensity cross-section which reducesthermal injury, increases the precision of the tissue interaction and allows the creation ofcraters with decreased sizes. Reflective optics provide precise, single-layer vaporizationat low power levels without thermal injury to the underlying papillary dermis. Movableoptical elements focus and direct the laser beam in a scanning pattern to treat a largearea of the surface.
