22/03/1960 Laser is patented

American physicists Arthur Schawlow and Charles Hard Townes patented the laser. However, another American, Gordon Gould, invented the same device independently of them. This led to the twenty-eight-year lawsuit. The term "laser" is an acronym for "light amplification by stimulated emission of radiation."
