The Laser (Civ3)/Civilopedia

Laser is an acronym for "Light Amplification by Stimulated Emission of Radiation". Lasers produce an amplified, coherent beam of light by 
using photons to energize or excite the electrons in the beam. Einstein first proposed the principles for the underlying theory of the stimulated 
emission of light in 1917. The first helium-neon gas laser was built in 1961. Years of research and development have led to a wide variety of 
laser applications in many different fields. Lasers can be used for everything from the precision cutting of almost any material and performing 
microsurgery to reading digital data and music information off of a compact disc. The military currently uses lasers for weapons targeting 
systems, and it has been proposed that laser technology could be used to defend against an enemy missile attack.
