What is the full form of LASER? LASER stands for Light Amplification by Stimulated Emission of Radiation. It is an electronic device that produces light, and these are actually electromagnetic radiations. These types of electromagnetic radiation are done through optical amplification.


History of LASER

Do you know, Albert Einstein was the first person to speak about the LASER process? The system was, however, fully developed in 1960 by Theodore H. Maiman and the LASER was based on the concept given by popular scientists Charles Hard Townes and Arthur Leonard Schawlow.



Below is a list of LASER types, based on their wavelengths and applications.

  • Gas LASER
  • Semiconductor LASER
  • Chemical LASER
  • Liquid or Dye LASER
  • Excimer LASER


Properties of LASER

We may classify the laser beam characteristics into these four main groups, such as:

  • Superior Coherence
  • Superior Monochromatism
  • High Output
  • Superior Directivity


Applications of LASER

  • LASERs are mostly used in DVD, CD and Barcode Scanners.
  • Lasers are used in different types of machinery devices, i.e. drilling, cutting, surface treatment, welding and soldering equipment.
  • Lasers are used in some medical devices such as dental treatment devices, cosmetic treatment equipment.
  • Lasers are also used in laser printing devices.
  • LASER is used in military equipment and Nuclear Fusion Reactors.


Advantages of LASER

It is used for information transmission in the field of communication because it has an enormous capacity to support information. Lasers are mainly used for the diagnosis of cancers in the medical sector because they are less harmful compared with X-rays. They are used to treat small tumours on the surface of the eye, and the surface of the tissue.


Disadvantages of LASER

  • Lasers are expensive, and therefore, those patients who need laser-based treatment options are much expenditure.
  • Increases complexity and duration of the treatment based on laser devices or equipment.
  • It is costly to maintain and hence more cost to doctors and hospital management.
