In-gas-cell laser spectroscopy of the isotopes ${}^{57,58,59,63,65}\mathrm{Cu}$ has been performed at the LISOL facility using the $244.164$-nm optical transition from the atomic ground state of copper. A detailed discussion on the hyperfine structure of ${}^{63}\mathrm{Cu}$ is presented. The magnetic dipole moments of the isotopes ${}^{57,58,59,65}\mathrm{Cu}$ are extracted based on that of ${}^{63}\mathrm{Cu}$. The new value $\mu =+0.479(13){\mu }_N$ is proposed for ${}^{58}\mathrm{Cu}$, consistent with that of a $\pi p_{3/2}\otimes \nu p_{3/2}$ ground-state configuration. Spin assignments for the radioactive isotopes ${}^{57,58,59}\mathrm{Cu}$ are confirmed. The isotope shifts between the different isotopes are also given and discussed.
