Super radiant emission or spontaneous coherent emission, is an emitted radiation with constant wave direction and rate that occurs in Fourier function. It is emitted when all electrons radiate in phase with each other, which generates the coherent radiation (super-radiant emission). It is emitted in a quantum mechanical system during a transition between two energy levels of molecules in a gas of dimension small compared to a wavelength. [1]
Assuming
where the electron-field excitation "transfer function" is defined by
Ensemble of of the total electrons in the beam is a stochastic process taking into account statistical distributions in phase space (special distribution, energy, and angular spreadings).
Solution of the mode amplitude together with equation of motion
enables one to calculate spontaneous and super-radiant emissions, including stimulated interaction resulting in amplification of the excited radiation as occurring in self-amplified spontaneous emission (SASE).
Instruments that uses the super radiant emission.
Superradiant emission using instruments such as FEL are used in materials science, chemical technology and surface analysis. Using the superradiant emission from the instruments, proteins molecules can be imaged. Another use of these instruments in the analysis is the vibrational energy transfer in molecule. High power from superradiant emission allows exciting molecule easier which also makes it easier to analyze the vibrational energy.
Superradiant emission using instruments are very advantageous because they produce high power laser due to coherent radiation and they do not use expensive photons.
For want of a better term, a gas which is radiating strongly because of coherence will be called 'superradiant'.
— Robert H. Dicke, 1954, [4]
Superradiance was discovered by American physicist named Robert H. Dicke. He discovered that coherent emission enhances the radiation. In the analytical instruments, superradiance is used to enhance the radiation emitted by the electron.
