Introduce the n-th order N-photon correlation functions. Reorganized to emphasize the N-photon emitter, now extended to the antibunching regime, rather than only coherent emission as previsouly

We propose a scheme based on the coherent excitation of a two-level system in a cavity to generate an ultrabright CW and focused source of quantum light that comes in groups (bundles) of N photons, for an integer N tunable with the frequency of the exciting laser. We define a new quantity, the purity of N-photon emission, to describe the percentage of photons emitted in bundles, thus bypassing the limitations of Glauber correlation functions. We focus on the case 1≤ N≤3 and show that close to 100% of two-photon emission and 90% of three-photon emission is within reach of state of the art cavity QED samples. The statistics of the bundles emission shows that various regimes---from N-photon lasing to N-photon guns---can be realized. This is evidenced through generalized correlation functions that extend the standard definitions to the multi-photon level.
