The stimulated emission process is based on four basic phenomena that occur in the laser generator: pumping, spontaneous emission of radiation, stimulated ...
Stimulated Emission – gain, amplification, amplifier, laser
Stimulated emission is a quantum effect, where photon emission is triggered by other photons. It is essential for the operation of lasers.
Spontaneous and Stimulated Emission - SPIE
If an atom is in an excited state, it may spontaneously decay into a lower energy level after some time, releasing energy in the form of a photon.
Stimulated Emission - an overview | ScienceDirect Topics
The word laser stands for “light amplification by stimulated emission of radiation,” which is the optical working principle behind its operation. Stimulated ...
Stimulated Emission | Lasers in Dentistry: Minimally Invasive ...
A laser beam is created from a substance known as an active medium, which when stimulated by light or electricity produces photons of a specific wavelength.

Why is stimulated emission required for a laser? - Quora
A key part of what makes laser light a 'thing' is coherence. The photons in the laser are the same wavelength *and* in phase with each other ...
In stimulated emission, another photon is absorbed by the atom, causing it to fall back to the ground state, with the release of two photons in ...
Spontaneous and Stimulated Emission: Definition and Measurement
Amplified spontaneous emission (ASE) serves as a reliable indicator of its potential. ASE is the process used by lasers to amplify light.
Stimulated emission
Stimulated emission is the process by which an incoming photon of a specific frequency can interact with an excited atomic electron, causing it to drop to a lower energy level.
Spontaneous emission
Spontaneous emission is the process in which a quantum mechanical system transits from an excited energy state to a lower energy state and emits a quantized amount of energy in the form of a photon.
