Laser stands for Light Amplification by the Stimulated Emission of Radiation. Lasers work by producing an intense beam of bright light that travels in one direction. The laser has the unique ability to produce one specific color or wavelength of light, which can be varied in its intensity and pulse duration. The newest laser systems have become remarkably precise and selective, allowing treatment results and safety levels not previously available. All lasers contain an energized …showed first 75 words of 1226 total…
