摘要：

A high-resolution two-photon spectrum of 5S(1/2) -> 5P(3/2) -> 5D(5/2) transitions in a thermal Rb-85 vapor cell is presented by using an optical frequency comb and a cw laser. The fluorescence of 6P(3/2) -> 5S(1/2) spontaneous emission is detected when the cw laser frequency is scanned from the 5S(1/2) ground state to 5P(3/2) hyperfine levels and the optical frequency comb repetition rate is fixed. The hyperfine splittings (F-f = 2-5) of the 5D(5/2) excited state are well resolved. The dependences of fluorescence intensities on the cw laser intensity and temperature of Rb-85 vapor cell are studied, respectively. The experimental results are in good agreement with the theoretical analyses.
