[BEST] Applications and Uses of LASER

use and applications of LASER

There is a huge application of LASER in Civil Engineering, Medical Industry, Meteorology, Printing Technology, Security system, etc. So here you will find a lot of applications and uses of LASER with explanations. LASER stands for Light Amplification by Stimulated Emission of Radiation.

LASER Applications

In modern days there is a huge application of LASER. Some important applications are explained below.

Electronic Communication

One of the most important applications of LASER is in Electronic Communication Systems. LASER is used as a data-transferring medium. Free Space Optical Communication or FSO communication is an example of the application of LASER in electronic communication.

Light Detection and Ranging(LIDAR)

In LIDAR technology applications LASER is also used as the source of light because laser is very powerful and it can generate very pure light of one color.

Application of LASER in Medical Industry

In the medical industry, for Surgery purposes, kidney stone removal treatment purposes, and hair removal treatment purposes LASER is used. Cancer treatment purpose LASER surgery is used.

Applications of LASER in Weapons

LASER Weapons can be damaged from a long distance. A LASER weapon called Dazzler can temporarily damage eyes or can cause temporary blindness. LASER is very helpful to aim or focus on the enemy very accurately.

Electronic Devices and Gadgets

Many electronic devices and gadgets use LASER. For example, light decorating devices, LASER printers, logo-making machines, laser lighting displays, laser counters, missiles, etc all use LASER.


Here some important uses of LASER are explained below.

Uses of LASER in Civil Engineering

1. For the testing purpose of the strength of construction of a building, LASER is used.
2. LASER is used to find or detect internal cracks in a building.
3. LASER is also used to detect bleeding in walls in multi-construction purposes.
4. It is also used to find and measure cracks and the angle or radius of bends of over bridges.

Use of LASER in Tunnel Excavations

LASER beam is very powerful which is why it is used for Tunnel or Underground Excavations. LASER can pulverize the rocks, in fact, it can turn the rock into gas. Modern Tunnel Machines use LASER technology. 3D LASER scanners are used for measurement purposes inside big tunnels.

LASER used for Water Vaporization

LASER can emit a very high amount of heat energy which is why it is also used for water vaporization purposes. The emission of heat energy from the LASER is dependent upon the wavelength. When a very high-powered LASER light is applied to water it will start to vaporize. The heat emission property of the LASER can also be used for burning of holes in a sheet of plastic or paper.

Use of LASER for Atom Cooling

LASER is used for the cooling purpose of the atom. For research purposes, this method is used. We know that atoms are constantly in motion. So the reduction of the motion of atoms is called atom cooling or cooling of atoms.

LASER consists of photons, so if the LASER is applied to the atom then it absorbs photons from the LASER beam, therefore, the velocity of the atom will decrease.

LASER used for cutting of Hard Metals

LASER is very powerful. High-power LASER beams can create very intense electric fields which can rip the atoms. For this reason, LASER is used for cutting of hard metals like diamonds.
