Optical Pumping of Rubidium Vapor Atoms

چکیده
The Zeeman splittings of the hyperfine structure of rubidium as well as the ambient geomagnetic field are investigated by using an optical pumping apparatus. The frequencies of Zeeman transitions are proportional to the magnetic field applied; using this, the ambient geomagnetic field is found to be B = ((37.755±0.025)ex+(5.5179±0.0030)ey +(19.15±0.06st±0.67sy)ez) ·10−6 T, compared to an accepted value of B = (48.499ex+3.242ey+19.770ez) ·10−6 T. Furthermore, the proportionality constant | h μBgf | (listed in 10−7 T kHz ) depends on which isotope of rubidium is considered: for Rb, the measured value is 2.083 ± 0.015st ± 0.002sy as compared to the accepted value of 2.143, while for Rb, the measured value is 1.387 ± 0.013st ± 0.005sy as compared to the accepted value of 1.429. Finally, extra absorption features are observed, and their values of | h μBgf | are twice the

Narrowband tunable filter based on velocity-selective optical pumping in an atomic vapor.
We demonstrate a tunable narrowband filter based on optical-pumping-induced circular dichroism in rubidium vapor. The filter achieves a peak transmission of 14.6%, a linewidth of 80 MHz, and an out-of-band extinction of >or=35 dB. The transmission peak can be tuned within the range of the Doppler linewidth of the D1 line of atomic rubidium at 795 nm. While other atomic filters work at frequenci...
متن کاملMagnetometers for space measurements over a wide range of field intensities
2014 The exploration of the earth’s magnetic field out to interplanetary regions has required magnetometers capable of measuring a wide range of field intensities. The past decade has witnessed considerable development of such instruments. Representative of these are the rubidium vapor magnetometer and fluxgates flown on OGO-5 by the Goddard Space Flight Center. For scalar measurements the rubi...
متن کاملNonlinear lensing mechanisms in a cloud of cold atoms
We present an experimental study of nonlinear lensing of near-resonant light by a cloud of laser-cooled rubidium atoms, specifically aimed at understanding the role of the interaction time between the light and the atomic vapor. We identify four different nonlinear mechanisms, each associated with a different time constant: electronic nonlinearity, Zeeman optical pumping, hyperfine optical pump...

متن کاملOptical pumping of rubidium atoms frozen in solid argon
We have grown crystals of solid argon doped with rubidium atoms. The spectrum of the implanted atoms depends on the crystal-growth temperature and annealing history. We have used optical pumping to polarize the spin state of the implanted atoms and polarization spectroscopy to detect the spin state and measure the spin-relaxation time. In addition to the desired optical pumping, we also observe...

There has been much interest recently in the effect of the propagation of a laser beam through dilute vapors of alkali metal atoms [1–5] due to their application in laser cooling [6,7], chip-scale atomic clocks and magnetometers [8,9], laser stabilization [10–12], and electromagnetically induced transparency [13]. In order to understand the spectra, several models have been proposed which accur...
