Nd:YAG
is an acronym for
neodymium-doped yttrium aluminium garnet (Nd:Y3Al5O12), a
compound that is used as the lasing medium for certain
solid-state lasers. The YAG crystal is doped with an active
medium, in this case triply ionized neodymium, which
replaces another element of roughly the same size,
typically yttrium. Generally the crystalline host is doped
with around 1 % neodymium by weight.
Types of YAG Laser

What is Laser?
Laser stands for Light Amplification by the Stimulated
Emission of Radiation(LASER).
A laser is a light beam that can be precisely focused. It
is used to treat tissues by heating the targeted cells
until they "burst". It may also be used for cosmetic
purposes, including removal of wrinkles, tattoos, or
birthmarks.
There are several types of lasers, including the carbon
dioxide (CO2) laser, the YAG (yttrium aluminum
garnet) laser, and the pulsed dye laser. Each laser
has specific uses. The color of the light beam used is
directly related to the type of procedure being performed
and the color of the tissue being treated.
Laser may be used to:
Remove tumors
Seal blood vessels
Seal lymph vessels to reduce swelling and decrease the
spread of tumor cells
Seal nerve endings to reduce postoperative pain
Remove warts, moles, and tattoos
Reduce the appearance of skin wrinkles
Remove hair
Possible side effects of
laser therapy:
Bleeding
Infection
Pain
Scaring
Skin color changes
