Laser (laser) is Light Amplification by the Stimulated Emission of Radiation.Idea of laser, as actionable back and, at the turn of the century in 1905, Einstein first light quantum hypothesis based on the theory of general relativity, and the idea of open the laser, followed in 1917, Einstein and stimulated radiation theory, put forward to accelerate the maturity of laser theory.Laboratory hughes companies in the United States in 1960, Mr Maiman Maiman engineers create the world's first ruby laser, followed by decades of laser all use very fast development, especially the most successful medical USES.
In dermatology field, the clinical use of laser types are: ruby laser, erbium laser, carbon dioxide laser, dye laser, ND YAG laser and alexandrite laser.According to its excitation is the name of the laser medium, there are thousands of substances in nature can be used to stimulate the laser light.Can generally be classified solid laser, liquid laser, gas laser and semiconductor laser.
Laser since the 60s is used for the treatment of skin disease, and in recent years with different wavelength laser, high-energy ultra pulse CO2 laser, variable pulse laser and erbium laser, etc.Let the laser cosmetic medicine beauty lifted a climax.
Laser is a kind of high-energy beam, to in a short period of time release energy, thermal effect on organization, selective damage;
