Working principle: 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 is a man-made crystal that is pumped by a high intensity lamp and placed into a resonator (a cavity capable of amplifying the power of the laser). By creating a variable long pulse duration and an appropriate spot size, it is possible to significantly heat deep skin tissues, such as large blood vessels and vascular lesions. Meantime the laser could heat the deep hair follicles while not damage the superficial skin tissue, so it's a most ideal choice for dark skin, especially the type IV-VI.
