Applications of pulsed energy sources and hydrodynamic response to materials science

Summary form only given. In order to address materials science applications involved pulsed beams, high-quality, energy deposition-hydrodynamic code techniques which can aid in the design and interpretation of experiments are being developed and used. These codes are capable of computing temperature, pressure, density, and dynamic quantities (material displacement and velocity), as a function of space (one-dimension) and time. However, they are not capable of calculating heterogeneous effects. In evaporative deposition of thin films the ion beam-target interactions may lead to 3-D, heterogeneous, material species and thermodynamic phases (including condensed phases) in the ablation plume which may compromise the quality of the film deposition. Consequently, the authors strongly encourage the development of 3-D, species selective diagnostic technqiues, e.g., resonant holographic interferometry spectroscopy for use in analyzing the ablation plume in thin-film deposition experiments.
