Huamei Alexandrite ND:YAG Laser for Dermatologic Applications and Hair Removal
The Huamei Alexandrite Laser System can be used for hair removal, to treat dermatological vascular lesions and other indicated dermatological applications. This unique Laser System contains two separate laser heads, an Alexandrite and ND:YAG(Neodymium-doped Yttrium Aluminum Garnet); which when pulsed produces laser light energy emitted at a nominal wavelength of 755 nanometers (nm) and 1064(nm) respectively. The outputs of each laser head are optically combined on the laser rail so that their beam paths are identical as they exit thelaser system.This allows the use of a single delivery system which can output either the 755 nm or 1064 nm wavelengths.
At these wavelengths, the Huamei Alexandrite Laser System causes maximum energy absorption by targeting specific chromophores in tissue. 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.
This process of targeting a specific chromophore (hemoglobin) is called selective photothermolysis. Ideally, the wavelength selected for eradiation of vascular lesions or hair is highly absorbed by the lesion or unwanted hair and only minimally absorbed by other competing chromophores in the skin. The laser pulse duration should be shorter than the thermal relaxation time of the target absorbing the laser radiation in order to confine the thermal damage and spare surrounding tissue. The relaxation time of a target is determined by size(milliseconds or greater for vascular lesions)
