LASER stands for Light Amplification by Stimulated Emission of Radiation. It is an electronic device that produces light, actually an electromagnetic radiation. This electromagnetic radiation is done through optical amplification.

History

The first theoretical foundation of laser was given by Albert Einstein in 1917 but the first laser was built in 1960 by Theodore H. Maiman at Hughes laboratory. It was based on the theory given by Charles Hard Townes and Arthur Leonard Schawlow.

Properties

The LASER radiation has very special properties that make them used in different type of applications. It is used to manufacture a wide variety of electronic devices like CD ROMs, Barcode readers etc.

The laser light is very thin and coherent.

Applications

• Used in CD and DVD ROMs.
• Used in Barcode Scanners.
• Used in integral part of Nuclear Fusion Reactors.
• Used in different type of devices i.e. cutting, drilling, surface treatment, soldering, welding devices.
• Used in medical equipments i.e. dentistry, cosmetic treatment devices.
• Used in Laser printing machines.
• Used in military equipments i.e. anti missiles devices.
