Title: Measurement of the 6d 2DJ hyperfine structure of cesium using resonant two-photon sub-Doppler spectroscopy
Author: Bragdon, T.; Masluk, N. A.; Kortyna, Andrew
Abstract: We report the hyperfine coupling constants for the 6d 2DJ states of 133Cs using two-color absorption spectroscopy with sub-Doppler resolution. Two single-mode diode lasers resonantly excite cesium in a low-pressure vapor cell. The frequency scale is directly referenced to the ground hyperfine interval of 87Rb using a radio-frequency modulation technique. The 6d 2D5/2 coupling constants are measured as A=−4.66±0.04 MHz and B=0.9±0.8 MHz, agreeing with the literature. The 6d 2D3/2 coupling constants are measured as A=16.34±0.03 MHz and B=−0.1±0.2 MHz, which significantly improve the precision of previous measurements.
