The full form of LASER is Light Amplification by Stimulated Emission of Radiation.
Understanding LASER Technology
A laser is a device that produces a highly focused and intense beam of light. This is achieved through a process called stimulated emission, where atoms or molecules are excited to emit light at specific wavelengths. This emitted light is then amplified within the laser cavity, resulting in a coherent and monochromatic beam.
Several sources confirm this definition:
- TechTarget: Defines LASER as "light amplification by stimulated emission of radiation," highlighting that lasers function due to resonant effects. https://www.techtarget.com/whatis/definition/laser
- Britannica: Describes a laser as a device that stimulates atoms or molecules to emit light at particular wavelengths, amplifying that light to produce a narrow beam. https://www.britannica.com/technology/laser
- Byju's: Explicitly states that the full form of LASER is "Light Amplification by Stimulated Emission of Radiation." https://byjus.com/full-form/laser-full-form/
- Wikipedia: Explains that a laser emits light through optical amplification based on stimulated emission of electromagnetic radiation. https://en.wikipedia.org/wiki/Laser
Applications of Lasers
Lasers have a wide range of applications across various fields, including:
- Medicine: Laser surgery, laser treatments for skin conditions, and diagnostics.
- Industry: Cutting, welding, and marking materials.
- Telecommunications: Fiber optic communication.
- Scientific Research: Spectroscopy, microscopy, and material analysis.
