摘要

Second-order coherence measurements can unambiguously determine whether a light source is generating coherent radiation,that is,whether it is a laser.In a systematic study reported by Kreinberg et al.,this measurement is used to additionally reveal intriguing physics associated with ultra-small resonators,such as the identification of sub-or super-radiance emission.
