In analogy with the static Stark effect, a quantum-mechanical degeneracy between the lower state plus one laser photon and the upper state can be lifted by increasing the intensity of the coherent light field. In order to avoid dissipative effects, this optical Stark effect is most clearly seen in semiconductors in a nonresonant experiment where the strong pump beam is tuned well below the lowest exciton resonance.

What is the Stark Effect? This article discusses the spectroscopic effect of strong electric fields known as the Stark effect, named for Johannes Stark, the first to experimentally demonstrate the effect. 2016-06-01 The Stark effect is the shifting and splitting of spectral lines of atoms and molecules due to the presence of an external electric field. It is the electric-field analogue of the Zeeman effect , where a spectral line is split into several components due to the presence of the magnetic field . 2021-04-09 · Stark effect, the splitting of spectral lines observed when the radiating atoms, ions, or molecules are subjected to a strong electric field.

Stark effect. The effect of an electric field on spectrum lines. The electric field may be externally applied; but in many cases it is an internal field caused by the presence of neighboring ions or atoms in a gas, liquid, or solid. Discovered in 1913 by J. Stark, the effect is most easily studied in the spectra of hydrogen and helium, by observing the light from the cathode dark space of an electric discharge.

It is the electric-field analogue of the optical Stark effect, and later compare with the quantum picture. 2.1 Semi-classical physics of the optical Stark effect Figure 1. (a) Energy level diagram of the static Stark effect in a two-level system.

The quantum-confined Stark effect describes the effect of an external electric field upon the light absorption spectrum or emission spectrum of a quantum well. In the absence of an external electric field, electrons and holes within the quantum well may only occupy states within a discrete set of energy subbands. Only a discrete set of frequencies of light may be absorbed or emitted by the system.
