- 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
- 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

- Лазер — Википедия
Ла́зер (от англ laser, акроним от Light Amplification by Stimulated Emission of Radiation — «усиление света посредством вынужденного излучения »), или опти́ческий ква́нтовый генера́тор, — устройство, преобразующее
- Laser - Light, Amplification, Coherence | Britannica
The combination of laser medium and resonant cavity forms what often is called simply a laser but technically is a laser oscillator Oscillation determines many laser properties, and it means that the device generates light internally
- Laser - Simple English Wikipedia, the free encyclopedia
A laser can be made so all the light travels in one direction, so the energy of the light stays as a narrow beam of collimated light that does not spread as much as in a flashlight (electric torch)
