  Superbunching pseudothermal light has important applications in studying the
second- and higher-order interference of light in quantum optics. Unlike the
photon statistics of thermal or pseudothermal light is well understood, the
photon statistics of superbunching pseudothermal light has not been studied
yet. In this paper, we will employ single-photon detectors to measure the
photon statistics of superbunching pseudothermal light and calculate the degree
of second-order coherence. It is found that the larger the value of the degree
of second-order coherence of superbunching pseudothermal light is, the more the
measured photon distribution deviates from the one of thermal or pseudothermal
light in the tail part. The results are helpful to understand the physics of
two-photon superbunching with classical light. It is suggested that
superbunching pseudothermal light can be employed to generate non-Rayleigh
temporal speckles.
