AB - <jats:p>Laser spectroscopy of the <jats:sup>229m</jats:sup>Th nuclear clock transition is necessary for the future construction of a nuclear-based optical clock. Precision laser sources with broad spectral coverage in the vacuum ultraviolet are needed for this task. Here, we present a tunable vacuum-ultraviolet frequency comb based on cavity-enhanced seventh-harmonic generation. Its tunable spectrum covers the current uncertainty range of the <jats:sup>229m</jats:sup>Th nuclear clock transition.</jats:p>
