Abstract

Doppler-free two-photon transitions of cesium 6S 1/ 2 → 7D 3/ 2, 5/ 2 were observed in a thermal stabilized cell. A repeated spectrum of 75 MHz introduced from the side band of an electro-optical modulator served as a frequency marker to improve the accuracy of frequency measurement. The hyperfine magnetic dipole constant A and electrical quadrupole constant B of Cs 7D 3/ 2, 5/ 2 can be derived from the splitting intervals of the observed spectra. The results are: A = 7.36(07) MHz, B =?0.88(87) MHz for the 7D 3/ 2 state, and A=?1.81(05) MHz, B = 1.01(1.06) MHz for the 7D 5/ 2 state. These coefficients are improvements for testing high-precision measurements and determining fundamental physical constants.
