In this paper, we investigate the generation of entangled light via collectively interacting three-level cascade atoms in a two-mode cavity. It is found that the atomic collectivity can effectively increase the strength of the frequency down-conversion process in the system and lead to the significant enhancement of the entanglement between the two cavity modes, in comparison to the case of independent atoms.
