Hyperfine Energy Level Splitting Structure Measurement of the Excited State 6D5/2 for Cesium Atom
Based on the ladder-type atomic system of cesium ( 133Cs) 6S1/2-6P3/2-6D5/2, a pump light with a wavelength of 852.335 nm or 852.356 nm and probe light with a wavelength of 917.483 nm were inversely arranged in a 133Cs vapor cell at room temperature. Accordingly, a double resonance absorption spectrum of 6P3/2-6D5/2 hyperfine energy level transition with narrow line-width and high signal-to-noise ratio is obtained. Subsequently, all the frequency intervals of the hyperfine energy level splitting structure of the excited state 6D5/2 are measured using a “ruler” built with an acousto-optic modulator. Finally, the hyperfine constants of magnetic dipole Ahfs and electric quadrupole Bhfs are obtained as (-4.59±0.06) and (-0.78±0.66) MHz, respectively, which agree with values reported in the literature.
