- Laser - Wikipedia
A laser differs from other sources of light in that it emits light that is coherent Spatial coherence allows a laser to be focused to a tight spot, enabling uses such as optical communication, [6] laser cutting, and lithography
- What Are Lasers And How Do They Actually Work? - ScienceAlert
The most powerful laser designed to date can be found at the European Extreme Light Infrastructure facility in Romania Its lasers are some of the most intense in the world, generating insanely brief pulses of photons, protons, neutrons, and neutrinos with incredible energy
- 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
- NIFs Guide to How Lasers Work
A laser is created when electrons in the atoms in optical materials like glass, crystal, or gas absorb the energy from an electrical current or a light That extra energy “excites” the electrons enough to move from a lower-energy orbit to a higher-energy orbit around the atom’s nucleus
