For energy so as to reach the purpose for removing or destroying destination organization, the pulse laser of various different wave lengths can treat various vascular skins
Skin disease and pigmentation, such as nevus of Ota, nevus flammeus, freckle, senile plaque expelling, telangiectasis, and go to tatoo, wash eye
Line, wash eyebrow, treatment scar etc..
Wherein Q-switch laser treatment system is very important part in laser beautifying, is according to " the selectivity of laser
Heat absorption " principle manufactures and designs, and exports the ps pulsed laser and ns pulsed laser of two kinds of wavelength of 1064nm and 532nm, can be by melanin and blood
Lactoferrin selective absorbing, pigment rapid expansion under the high-energy effect of laser, explosion smashes into little particle, and excludes body
Outside, and its hetero-organization of human body is minimum to the laser absorption of both wavelength, and therefore, the equipment can not damage surrounding tissue
Under the premise of highly desirable dispel pigment and the vascular tissue of lesion, other skin friendly positions, avoid scar and skin injury.
But Q-switch laser also has a shortcoming, for Q-switch laser output pulse width typically in 10ns or so, it is deeper to be applied to depth on skin,
Meeting permeate through epidermis and corium, are applied to hypodermis, while can produce substantial amounts of heat, cause area for treatment redness and pain.
Picosecond laser pulsewidth only has tradition to adjust 1 the percent of Q nanosecond lasers, and under this ultrashort pulsewidth, luminous energy has little time to turn
Heat energy is changed to, is nearly free from photo-thermal effect, and very fast expansion occurs for volume after being absorbed by target, producing photomechanical effect should
Torn and fragmentate by explosion, selectivity is stronger, and pigmentosa skin lesion can be made to produce stronger treatment under shorter treatment number of times
Effect, simultaneously because pulsewidth is shorter, the depth as shallow being applied on skin, hypodermis nerve will not be damaged, so pain is slight.
