LASER Full Form

What is The Full Form of LASER?

The term LASER stands for Light Amplification by Stimulated Emission of Radiation. It is a device that stimulates atoms or molecules in a way such that the light of some specific wavelengths are produced. Generally, it covers a limited range of visible, infrared or ultraviolet wavelengths.

Many different types of devices have laser and the characteristics have been developed over the years. The rays produced by these gadgets have been beneficial for humans, so they have used these in several different ways.

History of LASER

Albert Einstein gave the first explanation of laser in 1917. However, Theodore H. Maiman made the first LASER device (check the full form of laser) in the year 1960. The feat was accomplished at the Hughes laboratory, and the theories of Charles Hard Townes and Arthur Leonard Schawlow helped to make the invention possible. Since then, there have been regular improvements in the LASER industry.

Principles Used in The Making of LASER

The process of working on a LASER device, can be understood from the principles used by the equipment. A LASER works on the rules of Quantum Mechanics. The principle states that atoms and molecules have a specific amount of energy stored in them, and this energy depends on the types of molecules and atoms used. Proper usage of this theory helps in the creation of different types of lasers.

Elements of LASER

The laser full form in English is Light Amplification by Stimulated Emission of Radiation. To work properly, it needs to have three essential elements. The three components that are critical for the proper functioning of any LASER are Lasing material or active medium, external energy source, and optical resonator.

Types of LASER

Over the years, people have recognized the importance the meaning of laser. This has, in turn, encouraged them to manufacture different types of LASERs. The following are some of the different types of lasers available in the market:

  1. Solid State LASER

  2. Gas LASER

  3. Dye or Liquid LASER

  4. Excimer LASER

  5. Chemical LASER

  6. Semiconductor LASER

Characteristics of LASER

There are several characteristics of a device that explain further the full meaning of laser. These are

  1. The beam of light produced is generally much narrower than that provided by other sources.

  2. Though a laser beam produces a point of light on the opposite wall, the alignment of the line is not perfect.

  3. The deviation depends on the distance between the two walls and the extent of diffraction suffered by the beam.

Applications of LASER

Some of the applications of (the full form of the laser abbreviation) Light Amplification by Stimulated Emission of Radiation are:

  1. Used for transmission and processing information

  2. Delivering a precise amount of energy

  3. Finds application in the imaging industry


You will also get details about the history, principles, elements, characteristics, and applications of LASER from the above sections. These pieces of information will help you to understand the importance of LASERs in human life.

FAQ (Frequently Asked Questions)

How Does A LASER Work?

A LASER device works by using a special type of light beam that is generated by electrical energy. Thus, the device once installed requires very less maintenance cost.

How Hot is A Laser Beam?

For a commodity to be hot, it must have matter. However, the laser beam is made up of photons and not matter. So it cannot have a high temperature in order to become hot.

How Can Laser Power Be Measured Correctly?

Experiments are conducted before installing LASER into the device having. These help to determine the LASER power. So, check out for more information regarding the laser full form in English.
