Sažetak
We introduce a method for determination of the absolute frequencies of comb lines within the optical frequency comb spectrum. The method utilizes the experimental and theoretical approach of the velocity selective optical pumping of the atomic ground state hyperfne levels induced by resonant pulse train excitation. The information on the laser pulse repetition frequency and carrier-envelope ofset are physically mapped onto the 87Rb ground state hyperfne level population velocity distributions. Theoretical spectra are calculated using an iterative analytic solution of the optical Bloch equations describing the resonant pulse-train excitation of 4-level 87Rb atoms. They are employed to fit the measured spectra and obtain the parameters of the frequency comb, thus providing a practical algorithm which can be used in real-time measurements.
