We determine $\Lambda_{\bar{\textrm{MS}}}^{(n_f=2)}$ by fitting perturbativeexpressions for the quark-antiquark static potential to lattice results for QCDwith $n_f=2$ dynamical quark flavors. To this end we use the perturbativestatic potential at the presently best known accuracy, i.e. up to ${\calO}(\alpha_s^4)$, in momentum space. The lattice potential is computed on a finelattice with $a \approx 0.042 \, \textrm{fm}$ in position space. To allow for acomparison and matching of both results, the lattice potential is transformedinto momentum space by means of a discrete Fourier transform. The value of$\Lambda_{\bar{\textrm{MS}}}^{(n_f=2)}$ is extracted in momentum space. Allsources of statistical and systematic errors are discussed. The uncertainty inthe value of $\Lambda_{\bar{\textrm{MS}}}^{(n_f=2)}$ is found to be smallerthan that obtained in a recent position space analysis of the static potentialbased on the same lattice data.
