Nonlinear optical interferometer
Applied Optics, 1982The interferometer described, based on the second harmonic generation of light, is useful in the contouring of refractive objects with large variations in optical depth. The device is a real-time common-path self-referencing interferometer that yields interferograms in the visible with an equivalent wavelength of the order of 50 microm.

The availability of coherent matter waves from Bose-Einstein condensates had led to the extension of atom optics from the linear to the nonlinear regime, in analogy with the developments in optics following the invention of the laser. We provide a tutorial introduction to this emerging field, emphasizing the role of collisions as a “nonlinear medium ...

Interatomic interactions can introduce nonlinear behavior into a system of trapped ultracold atoms, similar to the dynamics of light propagating in a refractive nonlinear medium. Bose-Einstein condensates are now providing the means for studying coherent nonlinear dynamics with dilute atomic systems.

Annual Review of Physical Chemistry, 2009
The past decade has witnessed the emergence of new measurement approaches and applications for chiral thin films and materials enabled by the observations of the high sensitivity of second-order nonlinear optical measurements to chirality. In thin films, the chiral response to second harmonic generation and sum frequency generation (SFG) from a single

Abstract The time-reversal symmetry breaking, that is the result of the presence of a magnetization, leads to a number of well-known magneto-optical effects like Faraday rotation in transmission and Kerr rotation in reflection. In nonlinear optics in the electric-dipole approximation optical effects, e.g.

Photorefractive nonlinear optics and optical computing
Optical Engineering, 1989This paper describes various nonlinear optical phenomena in photorefractive media and selected applications in optical computing. These phenomena include optical phase conjugation, two- and four-wave mixing, and real-time holography. The applications include image amplification and subtraction, logic and matrix operations, and optical interconnection.

Nonlinear Optics of Bessel Beams
Physical Review Letters, 1993We investigated the frequency-doubling properties of light beams whose transverse profile is given by the zero-order Bessel function ${\mathit{J}}_{0}$(r), Bessel beams. Phase-matched second-harmonic generation in a KDP crystal was observed at angles usually not suited for phase matching.

We identify an aerosol of dielectric particles as a broadband, low-power nonlinear-optics medium. We demonstrate theoretically that a room-temperature volume of 5-μm-radius glass spheres will exhibit a third-order susceptibility in the visible equal to ~10f esu, where f is the volumetric packing fraction of the spheres.
