We consider two analytic representations of the SU (1,1) Lie group: the representation in the unit disc based on the SU (1,1) Perelomov coherent states and the Barut - Girardello representation based on the eigenstates of the SU (1,1) lowering generator. We show that these representations are related through a Laplace transform.
