Picosecond laser theory
Adopting 755 wavelength laser with honeycomb instantaneous lens to make 70% of the laser energy collection focus Each laser provides 10% of the skin tissue of high-performance shock effect, shatters skin layer of melonoma cells. Sasser wave is conduction to the deep epidermis, starts the skin repair mechanism to promote the growth of collagen and elastic fibers. Accelerate the skin’s mentalism, so that the melanin is excreted in accelerated metavolism, from the root to solve the melanin. Picosecond laser crashes melanin effect comparison.
THE PRINCIPLE OF “SELECTIVE PHOTOTHERMOLYSIS”
The principle of “selective photothermolysis” the shorter the laser action time, the target tissue to absorb the accumulation of laser energy is less likely to spread to the surrounding tissue, the energy was limited extent in the target treatment needs to protect the surrounding normal tissue, so the treatment of the stronger the selectivity, picosecond laser pulse width is only one hundredth of the traditional Q-switched nanosecond laser, its excellent performance to ensure the picosecond laser pulse crushing of pigment particles more thoroughly, while the surrounding tissue damage.
