Claim Text:
1. An apparatus for treating skin comprising: a source of a beam of radiation; a modulator receiving the beam of radiation and forming a modulated spatial profile of the beam including a first plurality of first regions at a first fluence and a second plurality of second regions at a second fluence, the first fluence being greater than the second fluence, each first region being spaced from an adjacent first region by a respective second region; and a device for delivering the beam of radiation to a target region of skin to cause a zone of thermal injury including a lateral pattern of varying depths of thermal injury distributed along the target region, the lateral pattern including at least one first sub-zone of a first depth of thermal injury laterally adjacent to at least one second sub-zone of a second depth of thermal injury, wherein (i) the first depth is greater than the second depth, (ii) the at least one first sub-zone of the first depth and the at least one second sub-zone of the second depth extend from a surface of the target region of the skin to form a substantially continuous surface thermal injury, and (iii) the at least one first sub-zone of the first depth and the at least one second sub-zone of the second depth are substantially heated to at least a critical temperature to cause the thermal injury.
