Superposition of Waves
The movie at left shows how a standing wave may be created from two travelling waves. If two sinusoidal waves having the same frequency (and wavelength) and the same amplitude are travelling in opposite directions in the same medium then, using superposition, the net displacement of the medium is the sum of the two waves.

Nondegenerate fourwave mixing in rubidium vapor ...
Fourwave mixing (FWM) is a nonlinear optical process that coherently combines three waves to produce a fourth one, and is used in many areas of physics. In atomic physics FWM is utilized to study spectroscopic and quantum optics processes [1–6]. It can generate specific frequencies not available with direct electromagnetic sources, and has

Photorefractives Tutorial FourWave Mixing
Fourwave mixing (FWM) geometry (on the right) is similar to that of the twobeam coupling. The difference is that in the FWM experiment, in addition to the writing beams 1 and 2, there is also a probe (reading) beam (beam 3) that is being partially diffracted from the grating created by the writing beams to create the fourth beam (beam 4).

Regenerative oscillation and fourwave mixing in graphene ...
coherent fourwave mixing—all at fewfemtojoule cavity recirculating energies. These observations, in comparison with control measurements on solely monolithic silicon cavities, are enabled only by the dramatically large and ultrafast x(3) nonlinearities in graphene and the large Q/V ratios in wavelengthlocalized photonic crystal cavities.

Mixing CPT University of California, San Diego
Global levels and patterns of mixing are hence set by the detailed geography of internal wave generation, propagation and breaking. Our Climate Process Team (CPT) was created to develop, test, and implement dynamically appropriate parameterizations for diapycnal mixing due to internalwave breaking for use in global climate models.

Conducting Excitation and Emission Spectra in the IR ...
We report new features of recently developed ultrafast coherent multidimensional spectroscopy (CMDS), an optical analogue to multidimensional NMR. By using both frequency and timedomain nonlinear four wave mixing methods, CMDS is able to directly observe coherence transfer (CT), the coherent quantum mechanical analogue of population relaxation.

OSA | Adiabatic fourwave mixing frequency conversion
We introduce the concept of adiabatic fourwave mixing (AFMW) frequency conversion in cubic nonlinear media through an analogy to dynamics in quantum twolevel systems. Rapid adiabatic passage in fourwave mixing enables coherent near photon number downconversion or upconversion over a bandwidth much larger than ordinary phasematching bandwidths, overcoming the normal efficiency ...
