Abstract: We report results on the laser cooling of ²⁴Mg⁺ ions to temperatures below 80 mK in a linear quadrupole Paul trap. A method has been demonstrated for determining secular frequencies of ions using amplitude modulation of cooling light, and vibrational spectra of simple ion crystals have been investigated.

Keywords: laser cooling, Paul ion trap, spectroscopy, dynamics of ions.
