We study the cooperative two-photon spontaneous decay of an excited atomic system in a microcavity whose size is of the order of several wavelengths of atomic radiation. We show that a thermalized electromagnetic field in the microcavity strongly affects the two-photon cooperative spontaneous emission of radiation. The increase in the rate of spontaneous cooperative decay is due to the presence of a small number of thermalized photons in a microcavity mode. At low temperatures, the two-photon absorption probability is found to be a linear function of the two-photon flux, and photon superbunching is observed.

We analyze the two-photon cooperative emission of excited atoms in microcavities with dimensions of the order of the emission wavelength. Here the two-photon dipole-forbidden transitions between the upper and the ground states of the three-level system are possible through the intermediate level that is off resonance with microcavity modes. In this situation one obtains the powerful pulse of two-photon highly correlated light. The superbunching phenomenon in radiated field is also discussed.
