The working principle and advantages of picosecond laser

          1.The working principle of picoseconds Everyone must have heard of picosecond lasers many times, but what does “picoseconds” mean? A picosecond is a unit of time, which is 10 minus 12 seconds, which can be understood as one trillionth of a second. The picosecond laser refers to the laser with the pulse duration (pulse width) of each laser emission reaching the picosecond level. It can be said to be the fastest laser in the world, 10,000 times faster than most traditional lasers. 


          2.The effect of picoseconds


          The pigment deposited on our skin is actually divided into different colors, such as red acne marks and brown spots. Compared with normal skin, these colored tissues can absorb some specific colors of light, while normal skin cells do not absorb this light. At the same time, due to the different causes of skin pigmentation, the layer depth is also different. Different wavelengths of light can penetrate deep into different skin layers and effectively combat pigmentation.


          Picosecond laser freckle removal uses its powerful instantaneous power to target the spots on the face by emitting light of a specific wavelength, so that it absorbs energy to produce a photothermal effect and explodes into smaller fragments. In order to achieve the effect of lightening pigment, whitening and rejuvenating skin. And in this process, due to the precise control of the instrument, the picosecond laser will not damage normal skin cells.

          3.Advantages of picoseconds


          1.Frequency The picosecond laser has a much faster emission speed than the traditional laser, which makes the picosecond instantaneous damage to melanin stronger, the course of treatment is short, and it will not cause repeated irritation to the skin. 


          2.Energy The picosecond laser can perfectly control three wavelengths for output. The wavelength of 755nm is the wavelength most absorbed by melanin, which can perfectly achieve the effect of gathering energy and crushing melanin. 


          3.Honeycomb The honeycomb picosecond is composed of hundreds of honeycomb focusing lenses to re-subdivide the highly concentrated laser beam into one by one laser beam, which achieves 20 times the therapeutic effect of ordinary laser. 




          The honeycomb focusing lens can focus the laser energy, release high-efficiency shock waves, and blast the melanin into dust, which is easier to be phagocytosed and decomposed by macrophages. At the same time, light waves can activate the growth factors of the skin, making the skin soft and white.
