Reading Time: <1 minuteToday, we gathered the staff and explained the absorption curve, which is one of the basics of laser principles. If the absorption curve is not well understood, the meaning of laser treatment will be lost. In the living body water red blood cells melanin pigment These three substances are the targets to consider when irradiating her laser. The principle of laser spot treatment is how to efficiently destroy melanin without damaging other targets. In addition to the wavelength, you must also consider the absorption rate of other targets. We perform treatment by considering various laser wavelengths, depth of penetration, and absorption targets. The longer the wavelength, the deeper the light travels The shorter the wavelength, the more shallow the light can reach. To this he adds doubts such as pulse width, energy. ·wavelength ·pulse width ·energy This is an important point for laser treatment. Q-switched YAG laser with a wavelength of 10 nm targets melanin in the epidermis Q-switched YAG laser with a wavelength of 6 nm targets pigmentary diseases of the dermis (ADM, nevus of Ota, tattoos, nevus flatus, etc.) The Q-switched ruby ​​laser has good absorption properties for melanin, and it is preferred by dermatologists because it has good sharpness when treating age spots. Recently, pico lasers with extremely short pulse widths have been actively used for tattoo removal and stain treatment. 20 minus XNUMXth power is pico XNUMX minus XNUMXth power is nano Q-switched YAG lasers also have a fairly short pulse width of XNUMX-XNUMX billionths of a second... Cutting-edge laser equipment continues to evolve.
