Tissue Interactions of Carbon Monoxide and Carbon Dioxide Lasers
The principle and the practical experimental results for the tissue interaction of CO and CO2 lasers are described in this chapter. The high-intensity irradiation of these lasers indicates strong cutting to the living tissue. Despite the fact CO2 lasers have been used as the unique light source for the laser scalpel, one problem remaining unsolved is the lack of available flexible optical fibers that can deliver CO2 laser radiation of 10.6 µm in wavelength. The CO laser radiation of wavelength 5 µm indicates similar tissue interaction to the CO2 laser radiation. Moreover, the flexible glass fibers made from infrared glasses can be available for CO laser delivery. We have recommended using CO lasers for cutting instead of CO2 lasers.
