- 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 | 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

When Theodore ("Ted") Maiman developed the first practical laser, few people realized how important these machines would eventually become Goldfinger, the 1964 James Bond movie, offered a tantalizing glimpse of a future where industrial lasers could slice like magic through anything in their path—even secret agents! Later the same year, reporting on the award of the Nobel Prize in Physics
- 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 First developed in the 1960s to amplify microwaves, modern lasers technology can ramp up light rays in just about any part of the electromagnetic spectrum, with the exception of gamma waves The

- Lasers: Understanding the Basics - Photonics
Over 60 years have passed since the first demonstration of a laser in 1960 After the initial spark of interest, lasers were for a while categorized as “a solution waiting for a problem,” but bit by bit, the range of their applications has expanded to encompass fields as diverse as DNA sequencing, consumer electronics manufacturing, or freezing the motion of electrons around atoms
