Primary symptoms: [3] perioral wrinkles, periorbital wrinkles, atrophic (depressed) scars, benign skin neoplasm (tumor); rough skin, large pores, fine wrinkles and other skin aging manifestations and inflammatory acne or acne scar, etc. Ultra-high-energy pulsed laser to heat the surrounding tissue to minimize the damage. Tiny wrinkles and sunken scars can also be precise grinding. Super-pulsed laser to avoid the previous mechanical dermabrasion, chemical peels bleeding, blood spatter, organizations can fine crumbs between the virus in the patient and the patient, communication between patients and medical staff such as lack of lesions through gasification to eliminate skin lesions, and make minimal thermal damage to normal skin, the role of time this process is faster than the surrounding normal tissue is also the time required for heating, functional wrinkles with microdermabrasion. s laser can emit laser device. 1954 made the first microwave quantum amplifier, to obtain a high degree of coherence of the microwave beam. 1958 AL Xiao Luo and CH Townes quantum amplifier theory to promote the use of microwave to optical frequency ...
... range, TH Maiman, who in 1960 made the first ruby laser. A. 1961, JIA, who made a helium-neon laser. 1962 RN Hall, who created a gallium arsenide semiconductor lasers. Later on more and more types of lasers. Divided by the working medium, the 100mW green laser pointer can be divided into gas lasers, solid-state lasers, semiconductor lasers and dye lasers 4 categories. Has recently developed a free-electron lasers, high-power lasers are usually pulsed output. It is the working directivity of green laser pointer.

In addition to free-electron lasers, the basic working principle of the laser are the same, resulting in an indispensable condition for the 50mW green laser pointer population inversion and the gain is greater than the loss, so the devices are an essential part of the excitation (or pumping ) source, with a metastable energy level of the working medium in two parts.Excitation energy is working medium after the absorption of external excitation to the excited state, to achieve and maintain and create conditions for population inversion. Incentives have optical excitation, electrical stimulation, chemical and nuclear energy incentives and other incentives. Metastable level with a working medium is so dominated by stimulated emission, in order to achieve optical amplification. Common component of the laser cavity as well, but the cavity (see optical resonator) is not an integral part of the cavity photon cavity can have a consistent frequency, phase and direction of travel, so that the laser has good direction and coherence. Moreover, it can work very well shorten the length of the material, but also by changing the cavity length to adjust the laser-generated model (ie, selection mode), it is generally lasers have cavity. 200mW green Laser Pointer sells well in the market.
