What Is A Long Pulsed Nd:YAG Laser?
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). 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.
How Does A Long Pulsed Nd:YAG Laser Work?
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 neocollagenesis which improves the appearance of facial wrinkles.
The Lumenis Long Pulsed Nd:YAG Solution
Lumenis’ long pulsed Nd:YAG laser is available as part of the M22™ multi-application platform.
By utilizing the same power supply for both the IPL and the Nd:YAG laser, Lumenis is able to provide more treatment versatility in a single platform.Multiple Sequential Pulsing (MSP™) is available in both the Nd:YAG and the IPL modules on the M22™ platform. MSP™ allows for cooling between a sequence of pulses which protects the epidermis and allows for safe use of higher fluence. The MSP™ offers safe treatment of all skin types, including dark skin, and significantly reduces side-effects in treatment of vascular lesions.
