Laser spectroscopy is a powerful tool to measure the basic properties of nucleus, such as nuclear spins, magnetic dipole and electric quadrupole moments, and charge radii, in a nuclear-model-independent manner. This is achieved by probing the subtle changes in the energy levels of electrons resulting from the interaction between the atomic nucleus and surrounding electrons. So far, the nuclear properties of more than a thousand isotopes have been studied by laser spectroscopy. These properties have made significant contributions in our understanding of exotic nuclei in different mass regions and offered prominent tests of state-of-the-art nuclear theory models. In this presentation, an introduction of laser spectroscopy method, examples on the study of exotic nuclei in several mass regions will be given. In addition, the recent progress on the development of the laser spectroscopy set up for the study of unstable nuclei at the radioactive ion beam facilities in China will be introduced.
