Direct spectroscopy of the SP and DP transitions and observation of micromotion modulated spectra in trapped \Ca
Thaned Pruttivarasin, Michael Ramm, Hartmut Haeffner
We present an experimental scheme to perform spectroscopy of the SP and DP transitions in \Ca. By rapidly switching lasers between bot…

Energy Transport in Trapped Ion Chains
Michael Ramm, Thaned Pruttivarasin, Hartmut Häffner
We experimentally study energy transport in chains of trapped ions. We use a pulsed excitation scheme to rapidly add energy to the local motional mode of one of the ions in the cha…

Precision Measurement Method for Branching Fractions of Excited P1/2 States Applied to 40Ca+
Michael Ramm, Thaned Pruttivarasin, Mark Kokish +2
We present a method for measuring branching fractions for the decay of atomic energy levels to lower-lying states based on time-resolved recording of the atom's fluoresce…
