Pb(Zr,Ti)O 3 (PZT) thick films were deposited onto stainlesssteel substrates by aerosol deposition using different kinds of carrier gases and were irradiated by CO 2 laser both during and after deposition, for the recovery of ferroelectricity. The ferroelectric and dielectric properties of PZT films deposited using oxygen and nitrogen gases and irradiated by CO 2 laser were superior to those of films deposited using He gas and irradiated by the laser. Some kinds of defects within the film were relaxed by CO 2 laser irradiation during deposition, and grain growth in the film was promoted by post-annealing using laser irradiation.
