- 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 . . .
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
- 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
- How do lasers work? | Who invented the laser?
How lasers work Before you can understand how a laser works, you need to know how an atom can give off light If you're not sure how this happens, take a look at the box how atoms make light in our introductory article about light A laser is effectively a machine that makes billions of atoms pump out trillions of photons (light particles) all at once so they line up to form a really
- 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
- What Is A Laser? | NIST
An explanation of lasers and their uses from NIST's William D Phillips, who shared the 1997 Nobel Prize in Physics for his pioneering work in using lasers to cool atoms to temperatures near absolute zero Dr Phillips leads NIST's Laser Cooling and Trapping Group, which continues to make fundamental discoveries in atomic, molecular, and optical physics, and is active in science education and
