The idea for the laser started as long ago as 1905 when Albert Einstein suggested the simulated emission of light. Light sources ie. candles, florescent substances, torches, and light bulbs give of packets of energy, called photons, when their atoms are excited by energy. Einstein suggested that these atoms could be artificially stimulated to emit photons, where the light produced would be highly concentrated, bright and powerful and could be used for many tasks. Even though Einstein new the principals for building a laser, it was not attempte ....
