NIF's Guide to How Lasers Work - Lawrence Livermore National Laboratory
A basic laser, like this red ruby laser, consists of a rod made of ruby crystals with a mirror on each end, and a flash tube. 2. A burst of light from the flash tube adds energy inside the rod, exciting the ruby atoms and producing light particles called photons. 3. The photons strike the atoms, creating more and more photons bouncing back and ...

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 is an anacronym that originated as an acronym for light amplification by stimulated emission of radiation. The first laser was built in 1960 by ...
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. Many different types of lasers have been developed, with highly ...
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 ...
