1. Apparatus for precision treatment of a material, comprising:

  • (a) laser diode array means for generating a plurality of laser light beams;

    (b) means optically coupled to said generating means for transmitting and combining said light beams;

    (c) means for scanning said combined light beams onto said material;

    (d) means for generating an optical image of said material;

    (e) means for receiving and processing said optical image to generate control signals for said laser diode array means and said scanning means, wherein said control signals for said laser diode array means control intensity and timing of said laser light beams, and said control signals for said scanning means control positioning of said scanning means to deflect said combined light beams onto said material as desired;

    (f) means for generating a thermal image of said material during and after the treatment; and

    (g) means for receiving and processing said image to generate control signals for said laser diode array means and said scanning means, wherein said control signals for said laser diode array means control intensity of said laser light beams over time, and said control signals for said scanning means control positioning of said scanning means to deflect said combined light beams onto said material as desired.
