We discuss the results of a study on the growth by laser ablation of YBa2Cu3O7 thin films on polycrystalline and annealed vicinal (001) MgO substrates. In both instances the filss were found to grow predominantly with the c axis normal the the plane of the substrate, regardless of the orientation of the MgO surface. In the case of vicinal substreats the films were found to have superconducting properties comparable to those obtained with fimls grown on (001) oriented, annealed singly-crystal substrates.
