LASERS AND ITS APPLICATIONS
Abstract:
A laser is an optical device that emits coherent light (electromagnetic radiation). The term 'laser' is an acronym for Light Amplification by Stimulated Emission of Radiation. Typically, lasers are thought of as emitting light in a narrow, low-divergence beam, with a narrow wavelength spectrum ('monochromatic' light). Lasers need not have either characteristic, however, it is the coherence of the laser's output that is distinctive. Most other light sources emit incoherent light, which has a phase that varies randomly with time and position.The first working laser was demonstrated on May 16, 1960 by Theodore Maiman at Hughes Research Laboratories. Since then, lasers have become a multi-billion industry. By far the largest single application of lasers is in optical storage devices such as compact disc and DVD players, in which a semiconductor laser less than a millimeter wide scans the surface of the disc. The second largest application is fiber-optic communication. Other common applications of lasers are bar code readers, laser printers and laser pointers. In science, lasers are used for many applications. One of the more common is laser spectroscopy, which typically takes advantage of the laser's well-defined
