LASER full form

LASER: – Light Amplification by Stimulated Emission of Radiation

A LASER emits light utilizing a process which is known as optical amplification. Light Amplification by Stimulated Emission of Radiation (LASER) is based on the stimulated emission of electromagnetic radiation.  It is a device or system which use a process i.e. stimulated emission. The stimulated emission process helps in generating the light. The light of Laser travels in a straight line. For the generation of laser light, mainly three processes are incorporated which are mentioned below:

  • Absorption
  • Stimulated emission
  • Spontaneous emission
  • Components of a Laser
  • The 3 basic components of a laser are following:-
  • Lasing material
  • Pump source
  • Optical cavity

The basic properties of LASER which make it more useful than other processes are mentioned below:

  • Highly monochromatic
  • Highly coherent
  • Highly directional
  • Highly focused

There are three types of LASERS and every type of LASER has a different application. The is also one of the features which makes it more demanding. The types are the following:

  • Solid State Laser
  • Gas Laser
  • Metal Vapor Laser
