Abstract:
1. A laser handpiece for generating radiation for treating tissue comprising: a housing; an elongated laser rod located within the housing; a laser resonator surrounding the rod; a flashlamp for pumping the rod to generate a beam of laser radiation; optics for focusing the beam onto the tissue wherein the optics include a diffractive optical element for splitting the beam into at least three spaced apart sub-beams and a lens assembly adjacent and closely spaced to the diffractive optical element without any beam steering elements therebetween, said lens system for directing the beams along separate paths and for focusing the sub-beams onto tissue in a linear array of spots; and a reflective scanner positioned between the resonator and the diffractive optical element for varying the entry angle of the beam and for translating the beam to different positions on the diffractive optical element to cause the sub-beams to be directed to different locations on the tissue.
