Working principle According to the principle of selective photopyrolysis,the shorter the laser's working time, the less energy the laser energy accumulated in the target tissue will spread to the surrounding tissue. The energy is limited on the target area to be treated, and the surrounding normal tissue is protected, so the selectivity of the treatment is improved and strong.The pulse width of the picosecond laser is only one-hundredth of that of the traditional Q-switched laser. Under this ultra-short pulse width, the light energy is too late to be converted into heat energy, and almost no photothermal effect occurs. The volume of the laser beam is rapidly expanded after being absorbed by the target, and rapidly being torn into pieces by blasting.The damage caused is smaller and the number of treatments is shorter, resulting in stronger efficacy. The rapid shock wave time of the Picosecond mechanical laser is superior to the general laser speed. The probability of thermal damage to the skin is greatly reduced, and the risk of stimulating melanin hyperplasia (anti-black) is also reduced. If we compare the original pigment particles to rocks, the traditional Q-switched laser can crush these rocks to the size of pebbles, and the picosecond laser can crush them to fine sand, so that the absorption efficiency of pigment fragments Greatly improved.
