In-gas-cell laser spectroscopy of the isotopes ^{57,58,59,63,65}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 ⁶³Cu is presented. The magnetic dipole moments of the isotopes ^57,58,59,65Cu are extracted based on that of ⁶³Cu. The new value μ=+0.479(13)μ_N is proposed for ⁵⁸Cu, consistent with that of a πp_3/2⊗νp_3/2 ground-state configuration. Spin assignments for the radioactive isotopes ^57,58,59Cu are confirmed. The isotope shifts between the different isotopes are also given and discussed.
