We theoretically analyze the optical response of an outgoing field in a -type three-level atom-assisted hybrid system with additional time-dependent external mechanical driving force applied to the mechanical resonator. Based on our analytical and numerical results, we report two optomechanically induced transparency windows that arise from tripartite (atom-photon-phonon) interaction. We show that by properly adjusting the time-dependent external mechanical driving force and relative phase value, the amplitude and width of optomechanically induced transparency windows can be significantly increased or decreased. We find that such control parameters are useful to study the influence of adjustable fast and slow light. Our proposed scheme provides new insights into the interaction between cavity quantum electrodynamics and atom-assisted optomechanical systems, paving the way for the development of optical memory devices.
