- 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

But what is a laser? What makes a laser beam different from the beam of a flashlight? Specifically, what makes a laser light different from other kinds of light? How are lasers classified? In this article, you'll learn all about the different types of lasers, their different wavelengths and the uses to which we put them (like laser pointers)
- 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

Because laser light stays focused and does not spread out much (like a flashlight would), laser beams can travel very long distances They can also concentrate a lot of energy on a very small area
- Lasers: Understanding the Basics - Photonics
All light sources convert input energy into light In the case of the laser, the input, or pump, energy can take many forms, the two most common being optical and electrical For optical pumping, the energy source may be a lamp or, more commonly, another laser
- Laser - Introduction - What is a Laser?
The word LASER is an acronym for Light Amplification by Stimulated Emission of Radiation Laser is a device that amplifies or increases the intensity of light and produces highly directional light
