Describe how a laser works.

Interpretation Introduction

Interpretation:

Working of a laser is to be described.

Concept introduction:

A molecule is a substance that is made up of two or more atoms. The molecule can be separated into a simpler substance by chemical means.

The process in which a fluid or a substance is dissolved or absorbed is called absorption.

The light that contains a single wavelength is called monochromatic light.

Amplification refers to amplifying or boosting a signal’s strength.

Excitation of electrons is the transfer of a bound electron from a lower energy state to a higher energy state (excited state) due to absorption of energy.

Explanation of Solution

Absorption of radiation, spontaneous emission, and stimulated emission are the three main principles behind the working of a laser. Absorption of radiation or energy from electrical energy ...
