The Laser Treatment

LLaser devices emit light using optical amplification process. Light Amplification by Stimulated Emission Process or LASER can be focused to pinpoint tiny spots. Launching lasers at low divergent beams concentrates their intensity at large distances. Single wavelength lasers are capable of launching radiation in a variety of modes. Some emit broad spectrum light or light at different wavelengths simultaneously. Laser devices are classified according to their formula of producing simulated emissions or light. Light refers to electromagnetic radiation regardless of its frequency and is not limited to visible light. Examples include infrared laser, X-ray laser and ultraviolet laser. The predecessor of the laser is the microwave laser or maser.   Laser energy...
