Nanoradian sensitivity Kerr effect apparatus
Review of Scientific Instruments, 1988The shot-noise limit to the sensitivity of ellipsometric phase shift measurements with a laser beam power of a few mW is of the order of 10−9 rad. An apparatus is described that realizes shot-noise-limited performance for dc Kerr effect birefringence measurements.

Chemical Physics Letters, 1993
Abstract The hyperpolarizability of H2 has been determined from measurements of the dc Kerr effect for H2 gas at T = 25°C and λ = 632.8 nm. The result of these measurements, λev = (4.48 ± 0.05) X 10−62C4 m4 J−3 (γev = 719 ± 7 au), is in fair agreement with the result of the most recent ab initio calculation for H2, γev = 726 au.

Nonlinear magneto-optical Kerr effects
Journal of Experimental and Theoretical Physics, 1999The polarization state of a second-harmonic wave after reflection from a semi-infinite, optically isotropic magnetic medium is considered for the three characteristic uniformmagnetization directions corresponding to the linear magneto-optical Kerr effects. Expressions for the complex amplitudes of the wave field which specify the nonlinear Kerr effects,

When a Raman active medium is irradiated simultaneously with an elliptically polarized pump laser beam of frequency oil and a linearly polarized Stokes laser beam as probe of frequency ωL ωs a Stokes component is produced which is perpendicularly polarized to the incident, probe beam.

Electrode effects from Kerr effect measurements
Conference on Electrical Insulation & Dielectric Phenomena - Annual Report 1986, 1986Previous papers {1,3} have shown good agreement between terminal current waveform measurements and current density waveforms from drift theory solutions. These measurements utilize parallel plate (stainless steel) electrodes (with spacing l = .34 cm) immersed in nitrobenzene (with permittivity e), and variable frequency with a peak voltage V 0 .

Kerr Effects of Flexible Macromolecules
1981Detailed calculations of the effects of different conformations on the Kerr constant have become available only recently. These calculations can be utilized to evaluate the usefulness of Kerr constant measurements in characterizing configurations of macromolecules. Experimental scientists would like to know, in particular, if Kerr measurements are more

Raman-Induced Kerr Effect Studies.
1980Abstract : The Raman-Induced Kerr Effect, developed at U.S.C. is a new form of laser spectroscopy which is beginning to find wide application as a remote diagnostic sensor of fast (picosecond to nanosecond) transient shocks, explosions, and plasma arcs.
