Abstract

We use electromagnetically-induced transparency (EIT) laser cooling to cool motional modes of a linear ion chain. As a demonstration, we apply EIT cooling on ²⁴Mg⁺ ions to cool the axial modes of a ⁹Be⁺-²⁴Mg⁺ ion pair and a ⁹Be⁺-²⁴Mg⁺-²⁴Mg⁺-⁹Be⁺ ion chain thereby sympathetically cooling the ⁹Be⁺ ions. Compared to previous implementations of conventional Raman sideband cooling, we achieve approximately an order of magnitude reduction in the duration required to cool the modes to near the ground state and significant reduction in required laser intensity.
