Via detailed analysis on several dominating noise sources, we have proposed solutions that significantly lower the MOKE noise, and a sensitivity of 1.5×10−7 rad/Hz is achieved with long-term stability. The sensitivity of the apparatus is tested by measuring …
Anomalous Kerr effect relaxation in an alternating field
Webhigh voltage technology, Kerr effect is very weak due to its low Kerr constant. Previous Kerr measurements have been using ac modulation technique, which is only applicable … WebThe Kerr effect, also called the quadratic electro-optic ( QEO) effect, is a change in the refractive index of a material in response to an applied electric field. The Kerr effect is distinct from ... c short condition

The Kerr effect, also called the quadratic electro-optic (QEO) effect, is a change in the refractive index of a material in response to an applied electric field. The Kerr effect is distinct from the Pockels effect in that the induced index change is directly proportional to the square of the electric field instead of varying … See more The Kerr electro-optic effect, or DC Kerr effect, is the special case in which a slowly varying external electric field is applied by, for instance, a voltage on electrodes across the sample material. Under this influence, the sample becomes See more DC Kerr effect For a nonlinear material, the electric polarization field P will depend on the electric field E: where ε0 is the vacuum permittivity and χ is the n-th order … See more • Kerr cells in early television (Scroll down the page for several early articles on Kerr cells.) See more The optical Kerr effect, or AC Kerr effect is the case in which the electric field is due to the light itself. This causes a variation in index of refraction … See more The magneto-optic Kerr effect (MOKE) is the phenomenon that the light reflected from a magnetized material has a slightly rotated plane of polarization. It is similar to the See more • Jeffree cell, an early acousto-optic modulator • Filament propagation • Rapatronic camera, which used a Kerr cell to take sub … See more WebMar 19, 2024 · The electrical resistance of the conductor with all its cross-sectional area in use is known as the “DC resistance.” The “AC resistance” of the same conductor refers to a higher figure resulting from the skin effect. As you can see, at high frequencies the AC current avoids travel through most of the conductor’s cross-sectional area.
