Resonance fluorescence and resonance Raman lineshapes in strong radiation fields
Abstract
A study is presented of lineshapes of three-level resonance Raman scattering and two-level resonance fluorescence in the presence of arbitrarily strong coherent radiation. The study is based on a tetradic scattering theory, and it rederives the Mollow lineshape for resonance fluorescence in the case of medium coupling strength to the radiation field. It was shown that relaxation can considerably alter the lineshape in resonance fluorescence through intermediate nonresonant levels; in the case of strong coupling, the collision rates are modified by the applied field. It is concluded that in resonance scattering, optical collision rates are directly obtained from linewidth measurements, while in self-attenuation spectra these rates can be obtained only from line intensity or line wing measurements.
