High-Precision Ramsey-Comb Spectroscopy Based on High-Harmonic Generation
L. S. Dreissen, C. Roth, E. L. Gründeman +3
High-harmonic generation (HHG) is widely used for up-conversion of amplified (near) infrared ultrafast laser pulses to short wavelengths. We demonstrate that Ramsey-comb spectrosco…
Paving the way for fundamental physics tests with singly-ionized helium
J. J. Krauth, L. S. Dreissen, C. Roth +4
High-precision laser spectroscopy of atomic hydrogen has led to an impressive accuracy in tests of bound-state quantum electrodynamics (QED). At the current level of accuracy many…
Benchmarking theory with an improved measurement of the ionization and dissociation energies of H
Nicolas Hölsch, Maximilian Beyer, Edcel J. Salumbides +4
The dissociation energy of H represents a benchmark quantity to test the accuracy of first-principles calculations. We present a new measurement of the energy interval between…
