An Nd:YAG laser is a solid state laser capable of producing a near-infrared wavelength that penetrates deep to 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). 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. Nd:YAG laser energy is selectively absorbed by the deeper levels of the dermis and allows for treatment of deeper vascular lesions such as telangiectasias, hemangiomas and leg veins. The laser energy is delivered using long pulses which are converted into heat in the tissue. The heat impacts the vasculature of the lesions. In addition, the Nd:YAG Laser can treat at a more superficial level; by heating the subcutaneous skin (in a non-ablative manner) it stimulates neo collagenesis which improves the appearance of facial wrinkles. Treat leg veins with long-pulsed 1064-nm light. The Nd:YAG 1064 laser handpiece coagulates and destroys large, deep, yet cosmetically unacceptable blood vessels and leg veins without the use of chemicals or needles. This easy-to-use, ergonomic handpiece effectively coagulates oxygenated reddish telangiectasias, as well as deoxygenated bluish venule ectasia and reticular veins up to 4 mm diameter. The long-pulsed 1064 nm Nd:YAG laser is able to penetrate deeper into the skin than lasers that use shorter wavelengths of light.
