Autler-Townes effect

Meanings

1. A dynamical Stark effect corresponding to the case when an oscillating electric field (e.g., that of a laser) is tuned in resonance (or close) to the transition frequency of a given spectral line, and resulting in a change of the shape of the absorption/emission spectra of that spectral line.

Etymology

Named after American physicists Stanley Autler and Charles H. Townes who discovered the effect in 1955.
