1. A method comprising:

  • using a first laser to generate a first beam of electromagnetic energy having a first wavelength on the order of 3 microns;

    using a second laser to generate a second beam of electromagnetic energy having a second wavelength on the order of 1 micron;

    coupling energy from said first laser to a metal halide optical fiber;

    coupling energy from said second laser to said metal halide optical fiber;

    guiding said energy having said first wavelength along said metal halide optical fiber at a dosage which cuts tissue;

    guiding said energy having said second wavelength along said metal halide optical fiber at a dosage which coagulates tissue;

    cutting tissue using said energy at said first wavelength; and

    coagulating tissue using said energy at said second wavelength.
