It stands for Light Amplification by Stimulated Emission of Radiation.
What does the world laser stand for?
Light Amplification by Stimulated Emission of Radiation
The letters in the word laser stand for Light Amplification by Stimulated Emission of Radiation.
How did laser get its name?
The word “laser” is 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.
What does the word laser stand for on what basic principle does it work?
stimulated emission
The principle of laser amplification is stimulated emission.
What is radiation in laser?
Some lasers emit radiation in the form of light. Others emit radiation that is invisible to the eye, such as ultraviolet or infrared radiation. In general, laser radiation is not in itself harmful, and behaves much like ordinary light in its interaction with the body.
Who named laser?
March 22, 1960: Townes and Schawlow, under Bell Labs, are granted US patent number 2,929,922 for the optical maser, now called a laser.

Which is the correct definition of Laser maser?
laser, optical maser(noun) an acronym for light amplification by stimulated emission of radiation; an optical device that produces an intense monochromatic beam of coherent light.
What do the different types of lasers do?
Many different types of lasers have been developed, with highly varied characteristics. Laser is an acronym for “light amplification by the stimulated emission of radiation.”
What is the acronym for high energy laser?
Laser is an acronym for “light amplification by the stimulated emission of radiation.”. PHELIX laserLearn about the PHELIX (Petawatt High-Energy Laser for Heavy Ion Experiments) laser at the GSI Helmholtz Centre for Heavy Ion Research in Darmstadt, Germany.
What is the meaning of laser?
Medical Definition of laser. (Entry 1 of 2) : a device that utilizes the natural oscillations of atoms or molecules between energy levels for generating coherent electromagnetic radiation usually in the ultraviolet, visible, or infrared regions of the spectrum.
How does a laser produce coherent light?
A laser produces coherent light through a process known as STIMULATED EMISSION. You may know that light is the result of spontaneous emission of a photon by an electron undergoing a transition in an atom.
What do lasers do?
Lasers work to amplify a light source and turn it into one powerful, concentrated beam. Electricity must be supplied to the laser through a power supply. Lasers can be powered through the use of batteries, electricity, or even another laser. Lasers also must have a medium that produces amplification of light.
What are the uses of laser light?
Laser light is useful in entertainment because the coherent nature of laser light allows a narrow beam to be produced, which allows the use of optical scanning to draw patterns or images on walls, ceilings or other surfaces including theatrical smoke and fog without refocusing for the differences in distance, as is common with video projection.
