  • Abstract
    The work reports the first direct frequency comb spectroscopy on trapped ions, calibrating the 4s 2Sm1/2- 4p 2P3/2 transition in cold 40Ca+. This one photon transition at 393 nm is relevant for the detection of a possible variation of the fine structure constant on a cosmological timescale. A comb at 393 nm is generated by frequency doubling of a Ti:Sa frequency comb at full repetition rate.
