What is the Full Form of LASER ?

LASER – Light Amplification by Stimulated Emission of Radiation

Light Amplification by Stimulated Emission of Radiation is an electronic device that produces light (electromagnetic radiation) through a process of optical amplification. These radiation have very special properties that makes them used in a wide variety of applications.

It is used to manufacture a wide range of electronic devices including CD ROMs, Bar code readers, etc. The light emitted by these devices is thin and coherent.

Applications of LASER

• It is used in CD and DVD ROMs.
• They are also used in barcode scanners
• Used as an integral part of nuclear fusion reactors
• In devices used for alignment, cutting, soldering, drilling, surface treatment, welding etc.
• In medical equipments for dentistry, cosmetic treatment etc
• In military equipments like anti missiles devices
• In Laser Printers for printing
