We explore the control of entanglement in a hybrid optomechanical system comprising an optical cavity with a mechanical end-mirror and a trapped intracavity Bose-Einstein Condensate (BEC). Pulsed laser light (tuned to be within realistic experimental conditions) is shown to induce an almost sixfold increase of the atom-mirror entanglement and to be responsible for an interesting dynamics between such mesoscopic systems. In order to assess the advantages offered by the proposed control technique, we compare the time-dependent dynamics of the system under constant laser pumping with the evolution due to the modulated laser light.
