Abstract
A dermatological treatment device is disclosed for generating a matrix of two dimensional treatment spots on the tissue. A handpiece carries a laser which generates a beam of laser pulses. The pulses are focused onto the tissue with a lens system. A diffractive element is positioned between the laser and the lens system for splitting the laser beam into a plurality of sub-beams. A scanner translates the beam over the diffractive element to generate the two dimensional spot pattern. The laser has a semi-monolithic resonator design with one integral end minor defining the output coupler and a second, independent mirror for adjustment.
