Faraday rotation density measurements of optically thick alkali metal vapors
نویسندگان
چکیده
We investigate the measurement of alkali number densities using the Faraday rotation of linearly polarized light. We "nd that the alkali number density may be reliably extracted even in regimes of very high bu!er gas pressure, and very high alkali number density. We have directly veri"ed our results in potassium using absorption spectroscopy on the second resonance (4 SP5 P). 2001 Published by Elsevier Science B.V. PACS: 32.80.Bx; 32.30.-r; 33.55.Ad

Elliptical polarization of near-resonant linearly polarized probe light in optically pumped alkali metal vapor
Optically pumped alkali metal atoms currently provide a sensitive solution for magnetic microscopic measurements. As the most practicable plan, Faraday rotation of linearly polarized light is extensively used in spin polarization measurements of alkali metal atoms. In some cases, near-resonant Faraday rotation is applied to improve the sensitivity. However, the near-resonant linearly polarized ...
متن کاملSensitive determination of the spin polarization of optically pumped alkali-metal atoms using near-resonant light
A new method to measure the spin polarization of optically pumped alkali-metal atoms is demonstrated. Unlike the conventional method using far-detuned probe light, the near-resonant light with two specific frequencies was chosen. Because the Faraday rotation angle of this approach can be two orders of magnitude greater than that with the conventional method, this approach is more sensitive to t...
متن کاملNonlinear magneto-optic polarization rotation with intense laser fields
We have studied the nonlinear Faraday effect with intense linear polarized light in an optically thick atomic rubidium vapor. We demonstrate that the polarization rotation rate rotation angle per unit magnetic field, in the limit of low field has a maximum value as the intensity and density are increased. We also show that the optimal sensitivity of an optical magnetometer based on this system ...
متن کاملFaraday rotation measures in 20 AGN jets at parsec scale
We present multi wavelength parsec-scale Faraday rotation measure properties of twenty active galactic nuclei, observed with the Very Long Baseline Array simultaneously at 1.4, 1.6, 2.2, 2.4, 4.6, 5.0, 8.1, 8.4 and 15.4 GHz in the full polarization mode. For the observed sources we construct Faraday rotation measure and Faraday-corrected linear polarization maps. Direction of electrical field i...
متن کاملHybrid optical pumping of optically dense alkali-metal vapor without quenching gas.
Optical pumping of an optically thick atomic vapor typically requires a quenching buffer gas, such as N2, to prevent radiation trapping of unpolarized photons which would depolarize the atoms. We show that optical pumping of a trace contamination of Rb present in K metal results in a 4.5 times higher polarization of K than direct optical pumping of K in the absence of N2. Such spin-exchange pol...
