We propose to measure the lifetime of short‐lived excited states in highly charged ions by pump‐probe experiments. Utilizing two synchronized and delayed Femtosecond pulses allows accessing these lifetimes with Femtosecond precision. Such measurements could provide sensitive tests of state‐of‐the art atomic structure calculations beyond the capabilities of established methods.
