- Laser - Wikipedia
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 originated as an acronym for light amplification by stimulated emission of radiation [1][2] The first laser was built in 1960 by Theodore Maiman at
- Laser | Definition, Acronym, Principle, Applications, Types - Britannica
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
- How do lasers work? | Who invented the laser? - Explain that Stuff
Lasers are amazing light beams powerful enough to zoom miles into the sky or cut through lumps of metal 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
- Lasers: Understanding the Basics - Photonics
Although lasers range from quantum-dot to football-field size and utilize materials from free electrons to solids, the underlying operating principles are always the same This article provides the basic information about how and why lasers work Over 60 years have passed since the first demonstration of a laser in 1960
- What Are Lasers And How Do They Actually Work? - ScienceAlert
Lasers are devices that concentrate beams of light by forcing their waveforms and frequencies to align First developed in the 1960s to amplify microwaves, modern lasers technology can ramp up light rays in just about any part of the electromagnetic spectrum, with the exception of gamma waves
- NIFs Guide to How Lasers Work
Lasers have been around since 1960, although the idea goes back to 1900 (see “A Legacy of Lasers and Laser Fusion Pioneers”)
- What Is a Laser? | How Is Laser Technology Used?
A laser is a device that emits a beam of coherent light through an optical amplification process There are many types of lasers including gas lasers, fiber lasers, solid state lasers, dye lasers, diode lasers and excimer lasers All of these laser types share a basic set of components
