Sub-milliKelvin spatial thermometry of a single Doppler cooled ion in a Paul trap
S. Knünz, M. Herrmann, V. Batteiger +3
We report on observations of thermal motion of a single, Doppler-cooled ion along the axis of a linear radio-frequency quadrupole trap. We show that for a harmonic potential the th…

Precision spectroscopy of the 3s-3p fine structure doublet in Mg+
V. Batteiger, S. Knünz, M. Herrmann +7
We apply a recently demonstrated method for precision spectroscopy on strong transitions in trapped ions to measure both fine structure components of the 3s-3p transition in 24-Mg+…

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…
