What is the Full Form of LASER?

LASER stands for "Light Amplification by Stimulated Emission of Radiation." It is a device that emits light through a process of optical amplification based on the stimulated emission of electromagnetic radiation.

 

Working Principle

 A LASER works by exciting atoms in a medium (solid, liquid, or gas) to a higher energy state, causing them to emit light when they return to a lower energy state. This light is then amplified and emitted as a coherent, focused beam.

Applications

• Medical: Surgery, eye treatment, dermatology.

• Industrial: Cutting, welding, engraving.

• Communication: Fiber optic communication, barcode scanners.

• Scientific Research: Spectroscopy, holography.

Advantages

• Precision: Highly focused and accurate beams.

• Efficiency: High energy efficiency and low waste.

• Versatility: Wide range of applications across different fields.
