Abstract

We present an experimental and theoretical investigation of two-photon direct frequency-comb spectroscopy performed through velocity-selective excitation. In particular, we explore the effect of repetition rate on the [formula] two-photon transitions excited in a rubidium atomic vapor cell. The transitions occur via stepwise excitation through the [formula] states by use of the direct output of an optical frequency comb. Experiments were performed with two different frequency combs, one with a repetition rate of [formula] MHz and one with a repetition rate of [formula] MHz. The experimental spectra are compared to each other and to a theoretical model.
