Dataset for Cavity-induced anticorrelated photon-emission rates of a single ion

<strong>Data for paper published in Phys. Rev. A 96, 023824 – Published 10 August 2017</strong> <br> <strong>Abstract</strong> <br> We report on the alteration of photon-emission properties of a single trapped ion coupled to a high-finesse optical fiber cavity. We show that the vacuum field of the cavity can simultaneously affect the emissions in both the infrared (IR) and ultraviolet (UV) branches of the Λ-type level system of 40Ca+ despite the cavity coupling only to the IR transition. The cavity induces strong emission in the IR transition through the Purcell effect resulting in a simultaneous suppression of the UV fluorescence. The measured suppression of this fluorescence is as large as 66% compared with the case without the cavity. Through analysis of the measurement results, we have obtained an ion-cavity coupling of ¯g0=2π×(5.3±0.1) MHz, the largest reported so far for a single ion in the IR domain. <br> <br> <br> <br>
