The term laser means light amplification by stimulated emission of radiation, and it uses a laser light source (laser beam) to remove tissues that are diseased or to treat blood vessels that are bleeding. Laser beams are strong beams of light produced by electrically stimulating a particular material. A solid, a liquid, or a gas is used. Alternatively, the laser is used cosmetically; it can remove wrinkles, birthmarks, or tattoos.
The special light beam is focused to treat tissues by heating the cells until they burst. There are a number of different laser types. Each has a different use and color. The color, or the light beam, relates to the type of surgery that is being performed and the color of the tissue that is being treated. There are three types of laser: the carbon dioxide (CO2) laser; the YAG laser (yttrium aluminum garnet); and the pulsed dye laser.
