Summary of "Long pulse 1064-nm neodymium-doped yttrium aluminum garnet (Nd:YAG) laser in aesthetic dermatology."

Long pulse 1064-nm neodymium-doped yttrium aluminum garnet (Nd:YAG) laser is a very versatile laser due to its deep penetration and absorption by hemoglobin, melanin, and, water, which has gained increasing popularity over recent years for the treatment of leg veins and permanent hair removal as well as skin rejuvenation. The long-pulse Nd:YAG laser was appointed as treatment of choice for the treatment of 0.5-3.0 mm deoxygenated, unsightly leg veins. Hair removal is another application of long pulse Nd:YAG lasers, and decreased light absorption by melanin at 1064 nm reduces the risk of pigmentary side effects, which makes long pulse Nd:YAG laser the safest laser in darker skin types. The long pulse Nd:YAG lasers are also being employed for skin rejuvenation based on their ability to heat dermal water and stimulate collagen production. We have reviewed the parameters of Nd:YAG laser and shared our experiences in these indications that may be useful for good clinical response with minimal side-effects.

Medical and Biotech [MESH] Definitions

Lasers which use a solid, as opposed to a liquid or gas, as the lasing medium. Common materials used are crystals, such as YAG (YTTRIUM aluminum garnet); alexandrite; and CORUNDUM, doped with a rare earth element such as a NEODYMIUM; ERBIUM; or HOLMIUM. The output is sometimes additionally modified by addition of non-linear optical materials such as potassium titanyl phosphate crystal, which for example is used with neodymium YAG lasers to convert the output light to the visible range.

An element of the rare earth family of metals. It has the atomic symbol Y, atomic number 39, and atomic weight 88.91. In conjunction with other rare earths, yttrium is used as a phosphor in television receivers and is a component of the yttrium-aluminum garnet (YAG) lasers.

Stable yttrium atoms that have the same atomic number as the element yttrium, but differ in atomic weight. Y-89 is the only naturally occurring stable isotope of yttrium.

Unstable isotopes of yttrium that decay or disintegrate emitting radiation. Y atoms with atomic weights 82-88 and 90-96 are radioactive yttrium isotopes.

Neodymium. An element of the rare earth family of metals. It has the atomic symbol Nd, atomic number 60, and atomic weight 144.24, and is used in industrial applications.
