For materials exhibiting a non-negligible Kerr effect, the third, ? ( 3 ) term is significant, with the even-order terms typically dropping out due to inversion symmetry of the Kerr medium.

Therefore beam intensities ( irradiances ) on the order of 1 GW cm " 2 ( such as those produced by lasers ) are necessary to produce significant variations in refractive index via the AC Kerr effect.
43.
The cubic nonlinear term on the right hand side is called Kerr effect, and is multiplied by "-j " according to the engineer's notation used in the definition of Fourier transform.

In optical Kerr effect ( OKE ) spectroscopy, optical heterodyning of the OKE signal and a small part of the probe signal produces a mixed signal consisting of probe, heterodyne OKE-probe and homodyne OKE signal.

Magnetic properties close to the surface of soft magnetic materials can be analysed using the Magneto-Optic Kerr Effect Potter ( MOKE ) which utilises the transverse Kerr effect to measure magnetisation loops in samples such as ferromagnetic films.

In fact, nonlinear optics effects can shift the resonant modes to improve the overlap with the perfect comb even more . ( The resonant mode frequencies depend on refractive index, which is altered by the optical Kerr effect .)
48.
Now let us assume we have a medium that shows only nonlinear Kerr effect but its refractive index does not depend on frequency : such a medium does not exist, but it's worth considering it to understand the different effects.
49.
A vector dissipative soliton could be formed in a laser cavity with net positive dispersion, and its formation mechanism is a natural result of the mutual nonlinear interaction among the normal cavity dispersion, cavity fiber nonlinear Kerr effect, laser gain saturation and gain bandwidth filtering.
50.
For example, Kuzyk's theory can be used to estimate how efficiently optical information can be manipulated in an optical fiber ( based on the Kerr effect ), which in turn is related to the amount of information that a fiber-optic system can handle.
