Laser - Wikipedia

https://en.wikipedia.org/wiki/Laser
Laser. A telescope in the Very Large Telescope system producing four orange laser guide stars. A laser is a device that emits light through a process of optical amplification based on the stimulated emission of electromagnetic radiation. The word laser is an anacronym that originated as an acronym for light amplification by stimulated emission

https://www.britannica.com/technology/laser/History
Laser - Invention, Light Amplification, Coherent Beam: The laser is an outgrowth of a suggestion made by Albert Einstein in 1916 that under the proper circumstances atoms could release excess energy as light—either spontaneously or when stimulated by light. German physicist Rudolf Walther Ladenburg first observed stimulated emission in 1928

Laser | Definition, Acronym, Principle, Applications, & Types

https://www.britannica.com/technology/laser
laser, a device that stimulates atoms or molecules to emit light at particular wavelengths and amplifies that light, typically producing a very narrow beam of radiation. The emission generally covers an extremely limited range of visible, infrared, or ultraviolet wavelengths. Many different types of lasers have been developed, with highly

Theodore Maiman - Wikipedia

https://en.wikipedia.org/wiki/Theodore_Maiman
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.

https://www.explainthatstuff.com/lasers.html
Although they seem pretty recent inventions, they've actually been with us over half a century: the theory was figured out in 1958; the first practical laser was built in 1960. At that time, lasers were thrilling examples of cutting-edge science: secret agent 007, James Bond, was almost chopped in half by a laser beam in the 1964 film Goldfinger .
