Four-wave mixing with matter waves The advent of the laser as an intense source of coherent light gaverist to monlinear optics,which now plays an important role inmany areas of science and technology.One of the first applicationsof nonlinear optics was the multi-wave mixi... L Deng,EW Hagl...
We have presented a semiclassical analysis of four-wave mixing in a system of two-level atoms interacting with a single-mode self-consistent classical electromagnetic field in the presence of a weak probe field. The relevant response functions for the probe wave as well as for the field generate...
Starting from a second-quantized Hamiltonian of many-particle systems, we derive the Gross-Pitaevskii (GP) equation in momentum space, which is suitable for studying the multi-wave mixing processes of coherent matter waves. The coupling equations are then applied to study ideal four-wave mixing (...
The nonlinear optical response (wave-mixing) was discovered in 1961 [1] right after the invention of the laser [2]. Since then this field has experienced a paramount growth and nowadays is exploited in a manifold of optical methods, with applications in almost all domains of science. Nonlinear...

Are not outside and inside indistinct, the edges merging into ecotones, rough and wild edges mixing with the cultivated, the mingling of field and forest, ocean and dune? Do we walk through this life with a constant question, for how can we answer any question with finali...

Keywords: four-wave mixing; optical parametric amplification Graphical Abstract1. Introduction Nonlinear optical effects have been investigated in various media for broadband light amplification. In particular, the optical parametric amplification via the second-order nonlinearity of a birefringent crystal has...
In DF combustion, gas is injected into the intake port; therefore, there is more time for the mixing process to generate a homogeneous pre-mixed mixture with fresh air for good combustion in the cylinder. A good mixing process results in a significant reduction in the local equivalence ratio ...
