Its Laser Day!!!

Yes its that time of the year again…its Laser Day!! Today marks the day when 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 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. Read more over at Wikipedia.
