1. A surgical method, comprising:

  • generating a first beam of pulsed electromagnetic energy having a first wavelength of approximately three microns;

    generating a second beam of electromagnetic energy having a second wavelength in a visible portion of the optical spectrum;

    generating a third beam of electromagnetic energy having a third wavelength of about one micron;

    coupling the electromagnetic energy of the first, second and third wavelengths to an optical fiber comprised of a compound that includes a metal such that said first, second and third wavelengths may be simultaneously transmitted through the optical fiber;

    simultaneously directing energy of said first, second, and third wavelengths from a distal end of the optical fiber against tissue;

    directing a fluid on said distal end of the optical fiber to cool said distal end;

    using the energy at the first and third wavelengths to perform cutting and coagulating of the tissue.
