Organizing and summarizing search results for youThe principle of a laser involves the following steps:- A basic laser consists of a rod made of crystals (e.g., ruby) with mirrors on each end and a flash tube.
- The flash tube adds energy to the rod, exciting the atoms in the crystal.
- The excited atoms emit light particles called photons.

Laser - Wikipedia
Electrons and how they interact with electromagnetic fields are important in our understanding of chemistry and physics.
In the classical view, the energy of an electron orbiting an atomic nucleus is larger for orbits further from the nucleus of an atom. However, quantum mechanical effects force electrons to take on discrete positions in orbitals. Thu…Wikipedia · Text under CC-BY-SA license- bing.com › videosWatch full video

Einstein recognized that this emission could be produced in two ways. Usually, discrete packets of light known as photons are emitted spontaneously, without outside intervention. Alternatively, a passing photon could stimulate an atom or molecule to emit light—if the passing photon’s energ… - However, if higher-energy configurations predominate (a condition known as population inversio…
The simplest conceivable system, such as the ammonia maser built by Townes, has only two energy levels. More useful laser systems involve three or four energy levels. In a three-level laser, the material is first excited to a short-lived high-energy state that spontaneously drops to a som…
