Abstract

We study coherent light scattering from linear crystals with up to twelve ⁴⁰Ca⁺ ions, acting as single photon emitters. Light scattering is induced by two-photon laser excitation, starting from the S1/2 → D5/2 quadrupole transition at 729 nm followed by the D5/2 → P3/2 dipole transition at 854 nm, from where the ions decay back to the S1/2 ground state via emission of a photon near 393 nm. We realize spin-selective excitation from the Zeeman-split ground states S1/2, m = ±1/2, of the Ca⁺ ions and observe, in the far-field, spin-dependent interference patterns displaying the spin textures of the ion crystals. We investigate their dynamics by measuring the temporal evolution of the spatial Fourier frequencies of the observed patterns.
