The energy levels of the hydrogen atom can be both calculated and measured very precisely. Precision spectroscopy on these transitions therefore, allows the determination of fundamental constants and testing the theory of QED for completeness.
Here we present the latest measurement of the 1S-3S transition, using two photon direct frequency comb spectroscopy. Its implications for the purposes mentioned above are shown together with additional measurements in hydrogen. Also we give an outlook on the next anticipated measurements, current problems and improvements of the experiment.
