The first working laser was demonstrated on May 16, 1960 by Theodore Maiman at Hughes Research Laboratories.[2] Since then, lasers have become a multi-billion dollar industry. The most widespread use of lasers is in optical storage devices such as compact disc and DVD players, in which the laser (a few millimeters in size) scans the surface of the disc. Other common applications of lasers are bar code readers, laser printers and laser pointers.
In industry, lasers are used for cutting steel and other metals and for inscribing patterns (such as the letters on computer keyboards). Lasers are also commonly used in various fields in science, especially spectroscopy, typically because of their well-defined wavelength or short pulse duration in the case of pulsed lasers. Lasers are used by the military for rangefinding, target identification and illumination for weapons delivery. Lasers used in medicine are used for internal surgery and cosmetic applications.
