We propose a new method of resonant enhancement of optical Kerr nonlinearity that uses multilevel atomic coherence. The enhancement is accompanied by suppression of the other linear and nonlinear susceptibility terms of the medium. We show that the effect results in a modification of the nonlinear Faraday rotation of light propagating in an 87Rb vapor cell by changing the ellipticity of the light. 相似文献

We show that the effective decay rate of Zeeman coherence, generated in a (87)Rb vapor by linearly polarized laser light, increases significantly with the atomic density. We explain this phenomenon as the result of radiation trapping. Our study shows that radiation trapping must be taken into account to fully understand many electromagnetically induced transparency experiments with optically thick media. 相似文献

The frequency of the dark resonance in coherent population trapping experiments has been measured as a function of the degree of ellipticity and the intensity of the probe light. The results have been used to find the quantum limit of sensitivity of an optical magnetometer based on the nonlinear Faraday effect. 相似文献

The carbon 1s binding energies (E
b) measured by X-ray photoelectron spectroscopy or obtained from quantum chemical calculations for 18 series of compounds in
which the reaction center is the C atom are analyzed. It was established for the first time that E
b values in carboncentered radical cations depend on the inductive, resonance, and polarizability effects of substituents. 相似文献

Stability constants at ionic strength I = 2 and 293 K were determined spectrophotometrically for multiligand bismuth(III) complexes with thiourea (Tu), N-phenylthiourea (Ptu), N-phenyl-N′-propylthiourea (Pptu), N,N′-diphenylthiourea (Bptu), and N-allyl-N′-propylthiourea (Aptu). The protonation constants of these ligands in perchloric acid solutions were also determined. The
stability of the listed complexes changes in the following order of ligands: aptu > tu > pptu > ptu > bptu. This order coincides
with the order of changing protonation constants.
