Low phase noise diode laser oscillator for 1S-2S spectroscopy in atomic hydrogen
N. Kolachevsky, J. Alnis, C. G. Parthey +3
We report on a low-noise diode laser oscillator at 972 nm actively stabilized to an ultra-stable vibrationally- and thermally compensated reference cavity. To increase the fraction…

Photoionization Broadening of the 1S-2S Transition in a Beam of Atomic Hydrogen
N. Kolachevsky, M. Haas, U. D. Jentschura +7
We consider the excitation dynamics of the two-photon \sts transition in a beam of atomic hydrogen by 243 nm laser radiation. Specifically, we study the impact of ionization dampin…
