Description: 

'Full Many a Gem of purest ray serene' has electronic-age implications never intended in Gray's Elegy as a result of man's first achievement of a 'coherent' light source, which could produce 'the purest colors ever known.' Dr. Theodore H. Maiman of Hughes Aircraft Company shows a cube of synthetic ruby crystal that forms the 'heart' of a laser (from Light Amplification by Stimulated Emission of Radiation), which generates the light. The light source (at top) is used to excite the tightly-packed atoms in the ruby which then amplify the laser's light into an intense parallel beam.
