The scaled coordinate method [1] is developed to treat molecules in intense laser fields. Specifically, we use it to solve the time-dependent Schrödinger equation for a reduced dimensionality model of HD^+ in a short, intense, linearly polarized laser pulse. We assume the molecule is aligned with the field, but cannot rotate. The problem is thus three dimensional (one nuclear coordinate plus two electronic). The utility of the scaled coordinate method for treating dissociation and ionization is determined, and comparisons with other methods will be presented. In addition, a variety of other numerical techniques will be developed and evaluated for treating this problem.
