Abstract
A laser based method for forming a superconducting oxide layer on various substrates is disclosed. The method comprises applying a dry salt precursor to the surface of a substrate and the heating the substrate by a laser beam which causes a superconducting oxide layer to be formed on the substrate without post annealing. An alternative embodiment comprises application of a salt solution precursor on the substrate surface. After the solution evaporates, the substrate is heated through laser energy and a superconducting oxide layer is formed on the substrate.
