Originally an acronym for "light amplification by stimulated emission of radiation;" the first functional laser was built by Theodore H. Maiman (1927-2007), and demonstrated in 1960. Lasers have multiple applications: they are used as components in information retrieval and transmission devices and systems, cutting, measuring, and medical tools, and as entertainment devices. ]]></dc:description></metadata>
