Can someone please give me a brief description of the AC Stark effect? What is it ?
It's the Autler-Townes effect. Apply constant electric filed to an energy level would result stark effect. Apply sinusoidal Electric filed would result AC stark effect.Nusc said:Can someone please give me a brief description of the AC Stark effect? What is it ?
The AC Stark Effect is a phenomenon in which an atom or molecule experiences a shift in its energy levels when exposed to an alternating electric field.
The AC Stark Effect occurs when the oscillating electric field of the light interacts with the electric dipole moment of the atom or molecule, causing a change in energy levels.
The AC Stark Effect is caused by an alternating electric field, while the DC Stark Effect is caused by a static electric field. Additionally, the AC Stark Effect is reversible, while the DC Stark Effect is not.
The AC Stark Effect is used in a variety of applications, including laser cooling and trapping, quantum computing, and spectroscopy.
The AC Stark Effect and the Zeeman Effect are both examples of light-matter interactions, but they have different causes. The AC Stark Effect is caused by an electric field, while the Zeeman Effect is caused by a magnetic field.
