Paper Abstract

Surgeon's hand, guiding a light ray, Laser, instead of holding a common lancet, for dissecting delicately tissues with simultaneous haemostasis on small vessels, represents one of the most interesting expressions of modern technology applied to surgery. The use of Laser in surgery dates back to 25 years ago. Its medical applications, however, are a little more recent. The word Laser comes from "Light Amplification by Stimulated Emission of Radiation". It • is known that any material, which has been stimulated, emits energy of excitation through the so called spontaneous Energy. This means irradiation of "quanta" of electro-magnetic energy untidily in space and time (so called "incoherent Emission"). A Laser source, conversely, emits "coherent" electro-magnetic radiations (so called "stimulated Emission") , whose characteristics consist in: monochromaticity,directional ity, coherence and brilliance.
