A specific nonlinear optical technique called second-harmonic generation ( SHG ) has been recently applied to the study of conformational change in proteins.

Because n-photon harmonic generation is essentially a scattering process, the emitted wavelength is exactly 1 / n times the incoming fundamental wavelength.
23.
Recent experiments using second harmonic generation of non-planar systems include transport kinetics across living cell membranes and demonstrations of SHG in complex nanomaterials.
24.
In many situations, an output pulse is generated by a nonlinear optical process, such as harmonic generation, continuum generation, or optical parametric oscillation.
25.
When this gets comparable to unity, significant nonlinear effects such as harmonic generation may occur, and, if large enough, may result in chaotic effects.
26.
Multiphoton microscopy ( MPM ) and second-harmonic generation ( SHG ) can be used to obtain high-resolution, noninvasive images of thick biological tissues.
27.
Recent advances include the use of High Harmonic Generation to capture images of molecular dynamics down to the scale of the attosecond ( 10 " 18 s ).
28.
In second harmonic generation this difference in frequency generation is a separated process in a cascade, so that the energy of the fundamental frequency can also be absorbed.

Lloyd Trammell and Elon Ray Coats filed for a patent on " Methods and apparatus for sub-harmonic generation, stereo expansion " on October 4, 2004.

Optical poling of silica fibers allows for second-harmonic generation through the creation of a self-organized periodic distribution of charges at the core-cladding interface.
