INTRODUCE
1. New application
It is superposition about the wavelength of 2940nm Er: YAG laser and the line of the water absorb. It is very famous be using in the surgical operation field. It is the known the best absorbed water (>3000cm ) in the laser field. It is a good assistant of the doctor.
2. Characteristic
A. No accessional light transfers channels (such as fiber).
B. The skin structure have a good absorb of 2940nm laser, It through the skin is very shallow, 170ms continue heat let the skin resume very fast, less pigmentation.
C. Spot size can be adjusted from 1 -8mm, It can abrade different skin.
D. Simple operation
3. Treatment
A. Abrade skin: Wrinkle removal, Scar removal.
B. Organic boil away: Splash, naevus, acne etc.
C. Sterilize

Theory
1. New application
It is superposition about the wavelength of 2940nm Er: YAG laser and the line of the water absorb. It is very famous be using in the surgical operation field. It is the known the best absorbed water (>3000cm ) in the laser field. It is a good assistant of the doctor.
2. Characteristic
A. The interaction of laser Organization
Thermal effect is the clinical application of the laser means a major role in the organization when the thermal effects on the surface, it will absorb a length in the direct heating, heat conduction through the heat relaxation to the surrounding tissue, was not conductive to the neighbouring organizations Near the surface can heat of vaporization or remove organizations. Removal organizations depend on the rate of laser energy in the organization of the aggregation. The higher the laser power, water vaporization and organizations removal faster, and minimize damage to the thermal cured net organizations than the speed of heat conduction below the surrounding tissue faster, which ensure that solidified the role confined to the laser absorption within the length.
Generally speaking, the first laser, the skin was white bubbly, this kind of change that cells within the vaporization of water, leaving dry protein debris, salt to the dry debris, the apparent shrinkage of the skin, The skin was pale yellow, these features such as mouth-thick skin more obvious. Upper eyelid skin thinner and other parts have not significantly shrink the Organization more than three times the apparent turn yellow radiation, visible to those with a tawny degeneration of dehydration protein substances, these substances on behalf of the dermis layer mesh degeneration of collagen protein, after further Will now charring and thermal diffusion, leading to necrosis.
B. Erbium: YAG Laser
Er: YAG laser can produce good water absorption of infrared 2940nm, using less than 250us pulse duration, Er: YAG laser each with more exposure to the organization, Er: YAG laser emission wavelength of 2940nm and the main water absorption Match the peak, the water absorption of carbon dioxide laser to 10 times, Er: YAG laser can let skin organization become thinner than CO2 laser, It can only penetrate the skin moist a few microns in depth, their skin in a time of relaxation 1-5ms, the extent of the damage stranded heat also very light, not vaporization of the Organization of the solidification of a thin layer, bleeding only needle size.
