摘要：

We demonstrate resonant fluorescence laser spectroscopy in highly charged ions (HCI) stored in an electron beam ion trap by investigating the dipole-forbidden 1s(2)2s(2)2p P-2(3/2)-P-2(1/2) transition in boronlike Ar13+ ions. Forced evaporative cooling yielded a high resolving power, resulting in an accurate wavelength determination to lambda = 441.255 68(26) nm. By applying stronger cooling and two-photon excitation, new optical frequency standards based upon ultrastable transitions in such HCI could be realized in the future, e. g., for the search of time variations of the fine-structure constant.
