Abstract
A method and apparatus are disclosed for laser treatment of surfaces, such as tissue. In a preferred embodiment, the invention employs a unique reflective optical delivery system which produces an improved beam intensity cross-section which reduces thermal injury, increases the precision of the tissue interaction and allows the creation of craters with decreased sizes. Reflective optics provide precise, single-layer vaporization at low power levels without thermal injury to the underlying papillary dermis. Movable optical elements focus and direct the laser beam in a scanning pattern to treat a large area of the surface.
