High-precision measurement of hyperfine structure in the D lines of alkali atoms
نویسندگان
چکیده
We have measured hyperfine structure in the first-excited P state (D lines) of all the naturally-occurring alkali atoms. We use high-resolution laser spectroscopy to resolve hyperfine transitions, and measure intervals by locking the frequency shift produced by an acousto-optic modulator to the difference between two transitions. In most cases, the hyperfine coupling constants derived from our measurements improve previous values significantly.

Precise measurement of hyperfine intervals using avoided crossing of dressed states
We demonstrate a technique for precisely measuring hyperfine intervals in alkali atoms. The atoms form a three-level Λ system in the presence of a strong control laser and a weak probe laser. The dressed states created by the control laser show significant linewidth reduction. We have developed a technique for Doppler-free spectroscopy that enables the separation between the dressed states to b...
متن کاملSecond-order effects on the hyperfine structure of P states of alkali-metal atoms
We analyze second-order M1-M1 and M1-E2 effects on the hyperfine structure HFS of the lowest-energy P states of alkali-metal atoms arising from the coupling of the two J=1 /2,3 /2 fine-structure levels through the hyperfine interaction. We find these effects to be especially sizable in Li, leading to a 9 correction to the most accurate reported experimental value of the A P1/2 HFS constant of L...
متن کاملDirect measurement of the fine-structure interval in alkali atoms using diode lasers
We demonstrate a technique for directly measuring the fine-structure interval in alkali atoms using two frequency-stabilized diode lasers. Each laser has a linewidth of order 1 MHz and precise tunability: one laser is tuned to a hyperfine transition in theD1 line, and the other laser to a hyperfine transition in the D2 line. The outputs of the lasers are fed into a scanning Michelson interferom...
متن کاملTheory of magic optical traps for Zeeman-insensitive clock transitions in alkali-metal atoms
Precision measurements and quantum-information processing with cold atoms may benefit from trapping atoms with specially engineered, “magic” optical fields. At the magic trapping conditions, the relevant atomic properties remain immune to strong perturbations by the trapping fields. Here we develop a theoretical analysis of magic trapping for especially valuable Zeeman-insensitive clock transit...
متن کاملShifts in the ESR Spectra of Alkali-Metal Atoms (Li, Na, K, Rb) on Helium Nanodroplets
He-droplet-induced changes of the hyperfine structure constants of alkali-metal atoms are investigated by a combination of relativistically corrected ab initio methods with a simulation of the helium density distribution based on He density functional theory. Starting from an accurate description of the variation of the hyperfine structure constant in the M-He diatomic systems (M=Li, Na, K, Rb)...
