Sciton Erbium YAG 2490 雷射去皺紋，老人斑
Erbium YAG is the newest of the lasers available for resurfacing facial wrinkles and scars. This technique provides decreased healing time and reduced redness of the skin following the procedure. This type of treatment can be used for superficial to moderate facial wrinkles, mild scars or splotchy discoloration. The Erbium YAG laser is also effective in treating sensitive sun damaged skin, without burning or scarring the delicate tissue around the eyes and mouth.
Er:YAG lasers are solid-state lasers whose lasing medium is erbium-doped yttrium aluminium garnet (Er:Y3Al5O12). Er:YAG lasers typically emit light with a wavelength of 2940 nm, which is infrared. Unlike Nd:YAG lasers, the frequency of Er:YAG lasers is strongly absorbed by water due to atomic resonances. This limits its use in surgery and many other laser applications where water is present. Because of this limitation Er:YAG lasers are far less common than relatives such as Nd:YAG and Er:glass.
Er:YAG lasers have been used for laser resurfacing. Example uses include treating acne scarring, deep rhytides, and melasma. In addition to water, Er:YAG laser energy is also absorbed by hydroxyapatite, which makes it a very good laser for cutting bone as well as tissue. Bone surgery applications have been found in oral surgery, dentistry, implant dentistry and otolaryngology.
