  • Theory of forward degenerate four-wave mixing in two-level ...

    A theoretical description for a forward degenerate four-wave mixing process in homogeneously broadened two-level absorbers with arbitrary intensities of all four beams is presented. Assuming no pump absorption and depletion, we obtain an analytical solution of forward degenerate four-wave mixing signal intensity in the limit of the strong pumps ...

    Doppler-free flame spectrometry based on resonant degenerate four-wave mixing (D4WM) is shown to be an effective analytical tool for the determination of barium at high spectral resolution. Optical phase conjugation is produced in an air/acetylene flame, resulting in an optical signal that is a coherent time-reversed replica of the probe beam.

    Phase-match in degenerate four-wave mixing (DFWM) is not automatically achieved in the forward folded boxcars geometry. In this paper, we first design a simple image aligning system composed of an optical system, CCD camera and the related software.

    Abstract: A quasi-collinear and partially degenerate four-wave mixing model is proposed to explain the optical phase-conjugation property of various types of stimulated backscattering. According to this model, after passing through a phase-disturbed medium or an aberration plate, the input pump beam can be resolved into two portions: a stronger undisturbed regular portion and a weaker phase ...

    Abstract: We report an investigation of the use of degenerate four-wave mixing (DFWM) to measure CH3 radical distributions in premixed hydrocarbon flames. Experimental results are compared with flame model calculations. By exciting the Herzberg _1 band near 217 nm, we monitored DFWM signals from CH3 as a function of height above a laboratory flat-flame burner at atmospheric pressure.

    For a stimulated degenerate four wave mixing process, two degenerate pump photons mix with a signal photon to gen-erate the idler photon. For an efficient frequency generation, the energy and the momentum should be conserved. Energy conservation can be written in terms of the pump l p, the signal l s and the idler l c photon wavelengths as 2 ...
