We have studied a possibility of the Bose condensate formation in a gas of photons, which are in thermodynamic equilibrium with the ideal gas of two-level Bose atoms below the degeneracy temperature. The coexistence conditions for the Bose-condensates in the atomic and photonic subsystems are found. The "avalanche" mode of condensation of photons is proposed. Such situation can be interpreted as "stopped light" in the Bose-condensate of atoms.

Keywords: Bose atoms, Bose–Einstein condensate, light, photons
