We present a novel method for detecting gravitons using an atomic gas supported by laser fields. Despite the coupling strength of gravitons to atomic transitions being orders of magnitude weaker than that of photons to atomic transitions, the rate of graviton-absorbed atomic transitions can be substantially elevated to a practically observable level. This enhancement is facilitated by an exceptionally potent amplification effect, stemming from a collective quantum electrodynamics phenomenon that encompasses a simultaneous multiphoton-multiatom process.
