ABSTRACT
Direct frequency comb spectroscopy of trapped ions is demonstrated for the first time. It is shown that the 4s ;{2}S_{1/2}-4p ;{2}P_{3/2} transition in calcium ions can be excited directly with a frequency comb laser that is up-converted to 393 nm. Detection of the transition is performed using a shelving scheme to suppress the background signal from nonresonant comb modes. The measured transition frequency of f=761 905 012.7(0.5) MHz presents an improvement in accuracy of more than 2 orders of magnitude.
