- 6. Device Description
The Long Pulse Nd:YAG Laser System is a flashlamp-excited, Nd:YAG (Neodymium-doped Yttrium Aluminum Garnet) laser system. Pulsed laser energy at a nominal wavelength of 10641m. This wavelength causes maximum energy absorption by targeting the treatment area and minimum absorption by surrounding skin structures. In addition, the laser pulse duration is controlled to be equal to or shorter than the thermal relaxation time of the target, to minimize heat transfer to surrounding tissues.

{5}------------------------------------------------

Deeper penetration and a more moderate hemoglobin absorption makes 1064 nm wavelength more useful for the deeper hair follicles and vessels. Further, with the right combination of parameters, the 1064 nm wavelength is also suitable for more superficial hair, telangiectasia and spider veins.

Base on this, Long Pulse Nd: Y AG Laser System is intended for 1) Benign pigmented lesions such as ,but not limited to , lemtigos (age spots), solar lentigos (sun spots), café au lait macules, seborrheic karatoses, nevi, chloasma, verrucae, skin tags, karatoses, tattoss (significant reduction in the intensity of black and/or blue black tattoos) and plaques. 2) Pigmented lesion size, for patients with lesions that would potiently benefit from aggressive treatment, and for patients with lesions that have not responded to other laser treatments. 3) Reduction of red pigmentation in hypertrophic and keloid scars where vascularity is an integral part of the scar.

The Nd: Y AG Laser System consists of control system, user interface, power source , laser emission and delivery system, cooling system and safety features
