An Nd:YAG laser is a solid state laser capable of producing a near-infrared wavelength that penetrates deep into the skin and is readily absorbed by hemoglobin and melanin chromophores. The lasing medium of Nd:YAG (Neodymium-doped Yttrium Aluminum Garnet) is a man-made crystal (solid state) that is pumped by a high intensity lamp and placed into a resonator (a cavity capable of amplifying the power of the laser).
