Abstract. We present an experimental study of seeded four-wave mixing (4WM) using a diamond excitation scheme (with states from the 5S 1 / 2, 5P 1 / 2, 5P 3 / 2 and 5D 3 / 2 terms) in a thermal vapour of 87 Rb atoms. We investigate the 4WM spectra under the application of a strong magnetic field (0.6 T).

We present an in-depth study of four-wave mixing (FWM) of optical pulses in silicon photonic crystal waveguides. Our analysis is based on a rigorous model that includes all relevant linear and nonlinear optical effects and their dependence on the group velocity, as well as the influence of free carriers on pulse dynamics. In particular, we reveal key differences between FWM in the slow- and ...

Froude Number and Flow States - Oregon State University

The Froude number is a measurement of bulk flow characteristics such as waves, sand bedforms, flow/depth interactions at a cross section or between boulders. The denominator represents the speed of a small wave on the water surface relative to the speed of the water, called wave celerity. At critical flow celerity equals flow velocity.

A four-wave mixing process of 4700 cm-1 Stokes-shift is stimulated by pumping a 20-cm commercial large-mode-area photonic crystal fiber with amplified Ti:sapphire femtosecond pulses. The phase-matching condition is realized through an intermodal scheme which promotes the process in the largely normal dispersion regime of the fiber.

Flow Regime - an overview | ScienceDirect Topics

The flow regime transition lines between stratified and intermittent or annular flow are obtained following the well-known wave-mixing mechanism developed by Milne–Thomson [1] and, later, Taitel [2].Only one of these flow regimes, stratified flow, will lead strictly to TLC, as annular and intermittent flow implies wetting of entire pipe surface with bulk liquid phase.
