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 ...

... exist yet. It was not until the 1950's where the stage was set to build a laser. Charles Townes, a scientist, wanted to see if microwaves, which are very similar to light, might be stimulated to produce an amplified beam by the process that Albert Einstein described. Townes was successful in 1954 when he constructed what he called the maser (microwave amplification by stimulated emission of radiation). The maser amplifies the number of photons that cause microwaves. After the invention of the mase ...
