Abstract
A method of treatment of skin tissue with two laser devices of unequal wavelengths comprising the steps of: (1) activating the two laser devices simultaneously to produce two laser beams of unequal wavelength; (2) directing the two laser beams into a handpiece having a distal tip to direct the laser beams onto the skin tissue; (3) directing the two laser beams within the handpiece to an adjustable beam deflector; and, (4) the adjustable beam deflector directing the two laser beams onto the skin tissue to produce a pattern of laser spots simultaneously but separated from one another.
