摘      要：High resolution two-photon spectrum of the transitions 6S_(1/2)→6P_(3/2)→8S_(1/2),9S_(1/2) and 6S_(1/2)→6P_(1/2)→7D_(3/2) in neutral ^(133)Cs are presented in a room-temperature vapor cell using a femtosecond optical frequency *** are obtained by scanning the repetition frequency of the femtosecond optical frequency comb over the two-photon hyperfine *** centroid frequency of the 6S_(1/2)→8S_(1/2),9S_(1/2),7D_(3/2) transitions are 729009798.80(17)MHz,806761363.96(11)MHz,and 780894762.595(23)MHz,*** hyperfine coupling constants of the corresponding states are also *** results are consistent with the previous measurements.
