What is Nd:YAG laser?
1.Nd:YAG (neodymium-doped yttrium aluminium garnet) is a crystal that is used as a laser medium for solid-state lasers.
2.The triply ionised neodymium [Nd(III)] dopant (ie a substance added in minute amounts to another pure substance to alter its conductivity), typically replaces a small fraction of the yttrium ions in the host crystal structure, since the two ions are of similar size.
3. The neodymium ion provides the laser activity in the crystal.
Nd:YAG laser has a wave length of 1064 nm and has the capability to reach deeper layers of skin tissue than other types of lasers.
4. In Q-switched mode, Nd:YAG produces 2 wavelengths, one in the infrared range (1064 nm) and a second beam of 532 nm wavelength which is useful for superficial skin lesions. Q-switching refers to the technique of making the laser produce a high intensity beam in very short pulsesParameterApplication
1. Tattoo removal. Remove black, blue, brown and red tattoo pigments on eyebrow, eye line, lip line and other parts of body; 
2. Remove birth mark, otas nevus and dermal speckle; 
3. The 1320nm wavelength: Skin whitening and tightening. 
4. The 1064nm wavelength: get rid of freckles, eyebrow tattoo, failed eye line tattoo, tattoo, Nevus of Ota, black and blue color and so on pigmentation;
5. The 532nm wavelength: get rid of freckles, eyebrow tattoo, failed eye line tattoo, tattoo , lips line, shallow red and brown pigment, telangiectasis and so on.
