This short article cannot cover that history in the detail it deserves..
Even though lasers have been here since 1943, lasers have evolved from the past microwave laser, to the various lasers, to the genetic changing laser.. A new time period of technology appeared in 1943 when two inventors named Charles Tow and Arth Schawlow invented the first maser..
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, although at the time it seemed to have no practical use.. In 1951 Charles H.. Townes, then at Columbia ..
The word LASER is an acronym that stands for “Light Amplification by Stimulated Emission of Radiation..” In 1917, Albert Einstein first described the theory of stimulated emission, whereby under the right circumstances, atoms could release excess energy as light—either spontaneously or when produced by light..
What is the origin of the word laser? The term "laser" originated as an acronym for "light amplification by stimulated emission of radiation".. The first laser was built in 1960 by Theodore H.. Maiman at Hughes Research Laboratories, based on theoretical work by Charles Hard Townes and Arthur Leonard Schawlow..
The word "laser" is an acronym for "light amplification by using inspired emission of radiation".. The first laser turned into constructed in 1960 with the aid of Theodore H.. Maiman at.. Evolution of the laser from the Nineteen Sixties Once the precept of laser technology was regarded, the entirety all at once went quicker in terms of improvement..
laser (n..) 1960, acronym for "light amplification by stimulated emission of radiation," on pattern of maser (1955).. A corresponding verb, lase, was coined by 1962..Related: Lasered; lasering..Laser disc recorded from 1980.. Earlier laser was the name of a type of gum-resin from North Africa used medicinally (1570s), from Latin; still earlier it was an Old English and Middle English name for some ..
The history of laser undoubtedly began in 1916 with Albert Einstein, who hypothesized that three processes essentially intervene in the formation of an atomic spectral line: spontaneous emission, stimulated emission and absorption.. To each of them he associated a coefficient (later called “Einstein’s”), which represents an estimate of the ..
VOA Special English, Explorations, The History of the Laser By VOA 05 February, 2013 Welcome to EXPLORATIONS in VOA Special English.. I'm Mario Ritter.. This week, we tell about one of the most recognizable objects in science fiction — the laser..
Applications.. Lasers are made use of in a wide variety of applications, such as in communication (fiber optics phone lines), entertainment (laser light shows), medical (removing lumps as well as cauterizing vessels in the retina), and in stores, grocery (bar code scanner).. Lasers can likewise be created by a huge variety of products, including ..

May 16, 1960: Theodore H.. Maiman, a physicist at Hughes Research Laboratories in Malibu, Calif.., constructs the first laser using a cylinder of synthetic ruby measuring 1 cm in diameter and 2 cm long, with the ends silver-coated to make them reflective and able to serve as a Fabry-Perot resonator..
The word LASER is an acronym that stands for “Light Amplification by Stimulated Emission of Radiation..” In 1917, Albert Einstein first described the theory of stimulated emission, whereby under the right circumstances, atoms could release excess energy as light—either spontaneously or when produced by light..
In Theodore Maiman’s first laser, a rod of man-made ruby supplied the electrons.. A more powerful version of the flash on a common camera was used to lift the energy state of the electrons ..
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 acronym [1] [2] for "light amplification by stimulated emission of radiation"..[3] [4] [5] The first laser was built in 1960 by Theodore H.. Maiman at Hughes Research Laboratories, based on theoretical work by Charles Hard Townes and ..
History of the Laser: The basic principle of laser is based on the Einstein’s theory of light proposed in 1916 which was later developed by Gordon Gould in 1957.. In 1960 Theodore Maiman invented the first working Ruby laser which was also the first optical laser apart from solids such as Ruby researchers have analyzed that some materials like ..

What were lasers originally used for? The first application for the ruby laser was for military range finders and is still used commercially for drilling holes in diamond because of its high peak power.. The Carbon Dioxide (CO 2) laser is developed by Kumar Patel at AT &T Bell Labs..) laser is developed by Kumar Patel at AT &T Bell Labs..
Lasers, as with many areas of physics, have a very rich history.. The word laser is actually an acronym; LASER stands for Light Amplification by Stimulated Emission of Radiation.. The origin of this somewhat complex sounding invention started with Einstein in 1917..
