I am doing some calculations to estimate the frequency of single-photon Rabi oscillations, and I am wondering if someone can give me an idea of how high these frequencies are, along with the energy levels used and approximate values of laser intensity.
Hi,
In the semi-classical treatment of light-matter interaction, the Rabi frequency turns out to be equal to Gamma*sqrt(I/2/I_sat) where Gamma is the natural linewidth of the transition, I_sat is the saturation intensity of the transition and I is the intensity of the laser.
Assuming that I=I_sat, the Rabi frequency is Gamma/sqrt(2). In the case of alkali atoms (widely used in laser cooling and trapping experiments), Gamma is about tens of MHz. So in this case the order of magnitude of the Rabi frequency is MHz.
Hope this will be helpful.
