One can interpret this nonlinear optical interaction as being analogous to a real-time holographic process.

This allows one to use the largest nonlinear coefficient of the material in the nonlinear interaction.

The nonlinear interaction mixes ultrasonic tones in air to produce sum and difference frequencies.

The bispectrum is a statistic used to search for evidence of nonlinear interactions in signals.

The bispectrum is a statistic used to search for nonlinear interactions.

They are characterized by a high peak intensity (or more correctly, irradiance) that usually leads to nonlinear interactions in various materials, including air.

Magnetic field of the tip and sample can change each other's magnetization, M, which can result in nonlinear interactions.

With current technology, you can get efficient nonlinear optical interactions, but the hardware is kind of bulky or very delicate.

As a result, the electric fields associated with the charge oscillation are quite intense-intense enough, in fact, to drive nonlinear interactions.

There is another set that consists of the signal fields that can be expressed using the form for the nonlinear interaction used in the measurement.
