Frequency Metrology on single trapped ions in the weak binding limit: The 3s1/2-3p3/2 transition in 24-Mg+
M. Herrmann, V. Batteiger, S. Knünz +3
We demonstrate a method for precision spectroscopy on trapped ions in the limit of unresolved motional sidebands. By sympathetic cooling of a chain of crystallized ions we suppress…
A stable fiber-based Fabry-Perot cavity
T. Steinmetz, A. Balocchi, Y. Colombe +4
We report the development of a fiber-based, tunable optical cavity with open access. The cavity is of the Fabry-Perot type and is formed with miniature spherical mirrors positioned…
Atomic Interferometer with Amplitude Gratings of Light and its Applications to Atom Based Tests of the Equivalence Principle
Sebastian Fray, Cristina Alvarez Diez, Theodor W. Hänsch +1
We have developed a matter wave interferometer based on the diffraction of atoms from effective absorption gratings of light. In a setup with cold rubidium atoms in an atomic fount…
High-Precision Optical Measurement of the 2S Hyperfine Interval in Atomic Hydrogen
N. Kolachevsky, M. Fischer, S. G. Karshenboim +1
We have applied an optical method to the measurement of the 2S hyperfine interval in atomic hydrogen. The interval has been measured by means of two-photon spectroscopy of the 1S-2…
