This paper studies the dynamical properties of the photon-added two-mode SU(1,1) coherent state in the Jaynes-Cummings-model. The dynamical behaviors of this state are found to be different compared to that of the corresponding two-mode coherent and two-mode SU(1,1) coherent states. The density operator of the photon-added two-mode SU(1,1) coherent state is presented using the dressed-state representation. By using the linear entropy criterion, the dynamical properties of the entanglement in this state are considered in detail.
