Optically pumped atoms
WebAug 3, 2012 · We present efficient theoretical tools for describing the optical pumping of atoms by light propagating at arbitrary directions with respect to an external magnetic field, at buffer-gas pressures that are small enough for velocity-selective optical pumping (VSOP) but large enough to cause substantial collisional relaxation of the velocities and the spin. …

WebApr 12, 2024 · The optical pumping beam is resonant with 5S 1/2, F = 2 to 5P 1/2, F ′ = 2 transition to polarize the atoms. The optical repumping beam is resonant with 5S 1/2, F = 1 to 5P 1/2, F ′ = 2 transition to pump most of the atoms to F = 2 states. Both optical pumping and repumping beams are split and sent to the two sensors (S a and S b) of the ...

For the convenience of the readers, we have set up an open-source Web site … WebIn an optically pumped alkali vapor cell with a high density of atoms, the attenuation of the pump light generates a spatially non-uniform distribution of the electronic spin polarization of alkali atoms, which is detrimental to biomagnetism applications of magnetometers as well as the hyperpolarization of noble gas atoms. Therefore, in this study, we propose a …
