Abstract
A method and apparatus for performing a medical or dental treatment by: providing radiation at two different wavelengths and at respective power levels such that the radiation at each wavelength is individually capable of cutting a given organic tissue; simultaneously applying the laser radiation at the two different wavelengths to a single body region which is composed of the given tissue; and directing a cooling fluid at the single body fluid region simultaneously with the step of applying radiation.
Claims14
Medical treatment apparatus comprising:
- laser means comprising
- first and second laser radiation sources each for producing laser radiation at a respectively different wavelength and power level capable of cutting a given organic tissue, each of said radiation sources comprising a respective laser radiation emitting body having a laser medium which determines the respective laser radiation wavelength, and
- optical pumping means disposed for supplying pumping energy to said bodies for causing said bodies to produce laser radiation, said optical pumping means comprising a first lamp optically coupled exclusively to one of said bodies, a second lamp optically coupled exclusively to the other of said bodies, and a third lamp optically coupled to both of said bodies;
- laser radiation applying means for directing laser radiation at body tissue to be treated;
- radiation conducting means including at least one optical fiber connected for conducting laser radiation from said sources to said applying means;
- and
- cooling fluid delivery means for directing a cooling fluid containing water at the body tissue at which the laser radiation is directed.
