A single-photon source based on a single Ca+ion

We propose a deterministic source of single photons based on the vacuum-stimulated Raman transition of a single Ca + ion trapped inside a high finesse cavity. Assuming realistic experimental parameters, the efficiency of photon emission into the cavity mode reaches 95%.
