Light Amplification by Stimulated Emission of radiation - Nanotechnology

What is Light Amplification by Stimulated Emission of Radiation?

Light Amplification by Stimulated Emission of Radiation, commonly known as LASER, is a process that generates a coherent beam of light through the mechanism of stimulated emission. In this process, an external energy source excites electrons in atoms or molecules to higher energy levels, and when these electrons return to their ground state, they emit photons. These photons stimulate other excited electrons to emit additional photons, creating a cascade of light amplification.

How is LASER integrated into Nanotechnology?

Nanotechnology leverages the principles of LASER to develop highly precise and efficient nanoscale devices and systems. By exploiting the quantum mechanical properties of materials at the nanoscale, researchers can design nanolasers, which are significantly smaller than traditional LASERs. These nanolasers can be used in a variety of applications, including optical data storage, medical diagnostics, and communications technology.
