Nonlinear processes in two-photon pumped atomic vapors
Technical Report
·
OSTI ID:6224722
A formalism suited for the study of two-photon resonant processes in atomic vapors is developed. Applications to the study of hyper-Raman scattering, four-photon parametric conversion and second-harmonic generation were carried out. Hyper-Raman scattering and four-photon parametric conversion were analyzed at steady state in the small-gain and saturation regimes. For the small-gain region, the results of perturbation theory are reproduced. The behavior of Stokes and idler fields in the saturation regime is shown to be in agreement with experimental results. Several characteristics of the line shapes experimentally observed are also qualitatively explained. A time-frequency analysis of the transients of the Stokes gain provides a method of studying the evolution of Stark shifts and dynamical Stark splittings, as well as constituting a valuable tool to distinguish between Raman-type and population-type lines.
