Fire the laser!

Ted MaimanAt the Hughes Research Laboratory in California, physicist Ted Maiman conducts the first completely successful laser demonstration, resulting in a brief pulse fired through a ruby. Though the concept of lasers had been published in the 1950s, Maiman is the first to develop a fully working test article. Within a few years, similar ruby lasers are used for numerous military applications, as well as early holography. Maiman’s test laser, when demonstrated again at a conference in 2010, is still operational.
