We intend to realize the step-up and step-down operators of the potential V(x) = V(1)e(2 beta x) + V-2(e beta x). It is found that these operators satisfy the commutation relations for the SU(2) group. We find the eigenfunctions and the eigenvalues of the potential by using the Laplace transform approach to study the Lie algebra satisfied the ladder operators of the potential under consideration. Our results are similar to the ones obtained for the Morse potential (beta ->-beta).
