Laser Science

The acronym of LASER is Light Amplification by Stimulated Emission of Radiation. According to physics light is an electromagnetic wave which has its own brightness and color. It vibrates at a certain angle, called polarization. The only difference in laser is it is parallel to other light sources. As the beams in the laser have almost exact same direction and so the beam will diverge very little. A good laser can illuminate the object at a distance of 1 km with a dot about 60 mm in radius. The lasers can be used to focus very small diameters where the concentration of light energy becomes so great that you can cut, drill or turn with the beam. The lasers can illuminate and examine very tiny details with lasers, thus it is used in surgical appliances and CD players as well. Lasers are monochromatic, so it has only one light wavelength.
