Hi all, I was wondering mathematically how stimulated emission works, could someone please explain it more concisely than wikipaedia? Thanks for any help...:shy:
Stimulated emission is a process in which an atom or molecule in an excited state releases a photon of the same energy and phase as the incident photon, resulting in the amplification of light.
Stimulated emission occurs when an external photon with the same wavelength and phase as the excited atom or molecule is introduced. This external photon stimulates the atom or molecule to release a photon of the same energy and phase, resulting in the amplification of light.
Stimulated emission is the basis for laser technology. In a laser, a medium such as a crystal or gas is excited, and then stimulated emission is used to produce a coherent, intense beam of light with a specific wavelength and phase.
Spontaneous emission is a random process in which an excited atom or molecule releases a photon without any external stimulus. On the other hand, stimulated emission is a non-random process in which an external photon stimulates the release of a photon of the same energy and phase as the incident photon.
Stimulated emission has numerous applications in various fields such as telecommunications, medical treatments, and materials processing. Lasers, LED lights, and optical amplifiers are examples of technologies that utilize stimulated emission.
