One and Two Photon Excitation of Radiofrequency Trapped Ca+

Radiofrequency (rf) trapped ions are versatile candidates for a large panel of applicationsranging from quantum information to the creation of cold molecules. Sample size can range from a single to 10^6 ions, and the internal and external energy states of the atoms can be controlled with high precision. In the experiment, we focus on different protocols related to frequency metrology using rf trapped Ca+.
