Four-photon parametric up-conversion in sodium vapor pumped with monochromatic and noise radiation under strong and weak dispersion conditions

Andrey V Aleksandrov, Vladimir S Solomatin

A theoretical investigation is made of the influence of various effects on four-photon parametric upconversion in metal vapors: saturation, one-photon absorption of output radiation, two-photon depletion of pump radiation, wave detuning, and dispersion of the group velocities of the interacting waves. Estimates indicate that the simultaneous influence of all these effects can ensure a fairly efficient up-conversion of noise pump radiation, compared with the monochromatic case. The results agree well with the experimental results obtained in a study of conversion of tunable CO2 laser radiation in sodium vapor.

Parametric noise in a nonlinear frequency up-converter of infrared signals by two-photon pumping of 3S–3Dand 3S–5Stransitions in sodium vapor

Yu A Galaĭchuk, Vladimir A. Kudryashov, V. L. Strizhevskiǐ +2 more

A systematic analysis was made of the spectral characteristics of resonance four-photon parametric conversion of infrared radiation as a result of two-photon resonance pumping of the 3S–3D and 3S–5S transitions in sodium and the influence of these characteristics on the threshold sensitivity of a parametric conversion detector was investigated. An experimental study was made of the characteristics of the noise radiation generated as a result of hyperparametric scattering. The results obtained can be used to select the optimal parameters of high-sensitivity detectors of weak infrared signals by parametric conversion in alkali metal vapors.
