“…Magnetic field dependent terms of the susceptibility decomposition which are nonlinear in the electromagnetic fields are responsible for NMOR. It can be demonstrated that only two-photon processes are important in this approximation, and therefore complicated multilevel systems may be reduced to systems with small level number (such as Λ, V , or X-schemes) [17,19,20]. * Electronic address: i.novikova@osa.org…”

“…Gawlik et al [25] observed strong narrow features in a forward scattering experiment with free sodium atoms, which were attributed to a hexadecapole moment. However, subsequent work of Giraud-Cotton et al [15] and other groups [17,19,20] demonstrated that these features may be explained using third-order perturbation theory which includes only quadrupole moments.…”

Nonlinear magneto-optical rotation of elliptically polarized light

We predict theoretically and demonstrate experimentally an ellipticity-dependent nonlinear magneto-optic rotation of elliptically-polarized light propagating in a medium with atomic coherence. We show that this effect results from hexadecapole and higher order moments of the atomic coherence, and is associated with an enhancement of Kerr and higher orders nonlinearities accompanied by suppression of the other linear and nonlinear susceptibility terms of the medium. These nonlinearities might be useful for quantum signal processing. In particular, we report an observation of an enhancement of the polarization rotation of elliptically polarized light resonant with the 5S 1/2 F = 2 → 5P 1/2 F = 1 transition of 87 Rb.

In this article, we review the history, current status, physical mechanisms, experimental methods, and applications of nonlinear magneto-optical effects in atomic vapors. We begin by describing the pioneering work of Macaluso and Corbino over a century ago on linear magneto-optical effects (in which the properties of the medium do not depend on the light power) in the vicinity of atomic resonances, and contrast these effects with various nonlinear magneto-optical phenomena that have been studied both theoretically and experimentally since the late 1960s. In recent years, the field of nonlinear magneto-optics has experienced a revival of interest that has led to a number of developments, including the observation of ultra-narrow (1-Hz) magneto-optical resonances, applications in sensitive magnetometry, nonlinear magneto-optical tomography, and the possibility of a search for parity- and time-reversal-invariance violation in atoms.Comment: 51 pages, 23 figures, to appear in Rev.

Nonlinear ring structures in forward scattering of resonant monochromatic laser radiation

We present experimental and theoretical investigations of a Gaussian laser beam interacting with Zeeman-tuned J=1-+J=0 atomic systems. In our experiment a single-mode cw dye-laser beam traverses a neon discharge in a longitudinal magnetic field. The excited neon transitions used for these studies are 1s4( J = 1, g = 1.464) -+2p3( J=0) and 1s2(J = 1, g = 1.034)~2p, ( J =0). In the laserinduced forward-scattered light, dark and bright ring-shaped structures are observed. The ring structures are investigated as a function of the magnetic detuning of the m =+1 sublevels and as a function of the laser-beam power. W'e find that the line shapes of the spectra, i.e. , the forward-scattered light intensities as a function of the magnetic detuning, are sensitive to the transverse intensity distribution of the laser beam. Analytical expressions based on a semiclassical theory are derived and the calculated results on the ring structures and the spectra are compared with the experimental results. Good agreement between the calculated and the experimental results are obtained only when the transverse effects are taken into account.PACS number(s): 32.80.Bx, 33.55.Fi
