Question

What are the important applications of lasers in science and technology?

Answer 1

Hint: Laser helps in the study of Brownian motion of particles. The rate of rotation of the earth is measured accurately by the laser.

Complete step by step answer:A device that generates an intense beam of coherent monochromatic light (or other electromagnetic radiation) by stimulated emission of photons from excited atoms or molecules, called lasers.
Important application of laser in science and technology:- Laser helps in the study of “Brownian motion” of particles. The He-Ne laser proved that velocity of light in all directions is the same. The rate of rotation of earth is measured accurately by the He-Ne laser.
Lasers help in counting the number of atoms in a substance. Lasers are used to separate isotopic species from the mixture of isotopes of elements in a substance.
The nature of plasma state of matter is studied with the help of lasers.
Lasers are also used to attain temperature which causes thermonuclear fusion of atoms.
Lasers are also used in holography which is a special three dimensional photography.
Lasers are also used in astronomy.
Lasers are used to study the nature of stellar objects and it also helped in extending distance of observation of objects.
The characteristic properties of lasers like high intensity and directionality have led to the development of new branch science called “Micro Raman Spectroscopy”. It is used to analyse small quantities of biological and biomedical samples.
Lasers are also used to retrieve stored information from a compact disc.
Laser also led to the development of a new method of communications called “Fiber-optic” communication.
Lasers are also used to measure pollutant gasses and other contaminants of the atmosphere. The branch of science is called “Atmosphere optics”.

Note:Laser is used in different aspects like:
1. Science and technology
2. Medicine
3. Industry
4. Defence and space science
Same as important applications of lasers in medicine, Industry and defence and space.
