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 (CO 2 ) laser; the YAG laser (yttrium aluminum garnet); and the pulsed dye laser.
