| Thousands of years ago man used handy
rocks for his surgical operations. Later he used sharp bone or horn, metal
knives and, more recently, rubber and plastic. And that was where we stuck, in
surgical instrument terms, for many years. In the 1960s a new tool was
developed, one which was, first of all, to be of great practical use to the
armed forces and industry, but which was also, in time, to revolutionize the art
and science of surgery. The tool is the laser and it is, being used by more and more surgeons all over the world, for a very large number of different complaints. The word laser means: Light Amplification by Stimulated Emission of Radiation. As we all know, light is hot; any source of light--from the sun itself down to a humble match burning--will give warmth. But light is usually spread out over a wide area.
