The ac stark shift
Did you know?
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. Although initially coined for the static case, it is also used in the wider context to describe the effect of … WebThe AC-Stark Shift Consider a many-level atom in its ground state jgiinteracting with a classical laser eld E~(t) = ~"E 0(t)exp(i!t)+ c:c, which has frequency !, polarisation vector …
The AC Stark effect was discovered in 1955 by American physicists Stanley Autler and Charles Townes while at Columbia University and Lincoln Labs at the Massachusetts Institute of Technology. Before the availability of lasers, the AC Stark effect was observed with radio frequency sources.
