4. Laser-human tissue interaction
During laser work, the beam may interact with the skin and/or eyes. The surface area of the skin is approximately 1.5 m 2 , but in general the accessible surfaces are limited to the face and hands. The size of the beam (usually a few cm 2 ) and the eye (of the order of a cm 2 ) reduce the probability of interaction. However, this "natural" protection is insufficient to prevent loss of vision.
4.1 Methods of destruction
For a user of laser sources, the physics of destruction are of secondary importance. By the time damage occurs, it's too late. The main damage modes
