Laser Ablation Analysis of 1-2-3 Material
Since the discovery of the Y-Ba-Cu-O material , several groups have investigated laser deposition techniques to produce superconducting thin films from the bulk 1-2-3 material [2–5]. We have performed laser ablation/evaporation research which supports the production of superconducting thin films. Control of the laser pulse and appropriate analysis of the vapor produced are necessary to understand the species that deposit on the substrate. Models for the laser-target interaction, the target plasma formation, and propagation to the substrate using a modified hydrodynamics code are presented.
