Photon indistinguishability constitutes an essential resource in modern physics. At the scale of individual atoms and photons, it is a diverse concept that causes different coherent phenomena. We present the experimental characterization of indistinguishable photons detected in a single mode from a finite and stable ensemble of single-photon emitters: trapped ions. We conclusively observe an increase of second-order correlation and super-Poissonian statistics of these photons with a number of contributing phase-incoherent independent emissions from the atoms, ranging from a single to up to several hundred. This optical emission regime provides insight into the emergence of super-Poissonian light at the atomic scale by photon indistinguishability. It constitutes a unique toolbox for its generation and control at the most microscopic level. (c) 2023 Optica Publishing Group under the terms of the Optica Open Access Publishing Agreement
