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.
