A laser (light amplification by stimulated emission of radiation) is a maser that works over a broader range of higher frequency photons in the ultraviolet and visible portion of the electromagnetic spectrum.
The invention of the maser (microwave amplification of stimulated emission of radiation) in 1954 by Charles Townes and Arthur Shawlow led to new investigations into light amplification by stimulated emissions of radiation, or laser, a term coined by American physicist Gordon Gould in 1957.
Theodore Harold Maiman (July 11, 1927 – May 5, 2007) was an American engineer and physicist who is widely credited with the invention of the laser. Maiman's laser led to the subsequent development of many other types of lasers. The laser was successfully fired on May 16, 1960

His playful demonstrations – putting a blue balloon inside a clear one and firing a laser to pop the balloon inside, or his efforts to create a laser out of Jell-O – led to our understanding of laser absorption and to innovations such as the distributed feedback laser.

First Working Laser, 1960. On this site in May 1960 Theodore Maiman built and operated the first laser. A number of teams around the world were trying to construct this theoretically anticipated device from different materials. Maiman’s was based on a ruby rod optically pumped by a flash lamp.
