Abstract

We report on the combined action of a cw diode laser and a train of ultrashort pulses when each of them drives one step of the 5S-5P-5D two-photon transition in rubidium vapor. The fluorescence from the 6P3/2 state is detected for a fixed repetition rate of the femtosecond laser while the cw-laser frequency is scanned over the rubidium D2 lines. This scheme allows for a velocity selective spectroscopy in a large spectral range including the 5D3/2 and 5D5/2 states. The results are well described in a simplified frequency domain picture, considering the interaction of each velocity group with the cw laser and a single mode of the frequency comb.
