Lasers designed to produce pulsed dye and Nd:YAG laser beams combined in one unit that are intended for dermatologic treatments. The beams produced by the laser with dye as an active medium usually operate at a wave length of 585 nm (yellow) while the radiation from the Nd:YAG laser (yttrium-aluminum-garnet crystal doped with neodymium) is at 1064 nm (near-infrared). The combined systems operate sequentially, the application of the laser dye beam previous to the Nd:YAG provides a qualitative different result in some dermatologic applications and capillary vascular malformations (e.g., port wine stains).
