Laser spectroscopy measurements have been carried out on very-neutron-deficient platinum isotopes with the COMPLIS experimental setup. Using the ${5d}^{9}{6s}^{3}{D}_{3}ensuremath{
ightarrow}{5d}^{9}{6p}^{3}{P}_{2}$ optical transition, hyperfine spectra of ${}^{182,181,180,179,178}mathrm{Pt}$ and ${}^{183}{mathrm{Pt}}^{m}$ were recorded for the first time. The variation of the mean square charge radius between these nuclei, the magnetic moments of the odd isotopes, and the quadrupole moment of ${}^{183}{mathrm{Pt}}^{m}$ were thus measured. A large deformation change between ${}^{183}{mathrm{Pt}}^{g}$ and ${}^{183}{mathrm{Pt}}^{m},$ an odd-even staggering of the charge radius, and a deformation drop from $A=179$ are clearly observed. Comparisons are made with microscopic theoretical predictions, in particular Hartree-Fock-Bogoliubov calculations using the Gogny force.
