Abstract

Various parameters affect the pulsed laser ablation of materials including the background gas and pressure. In this work, a numerical model is used to show the microscopic influence of direction of the background gas as well as sampling velocities from various probability distributions. Common observations from the various probability distribution are lighter elements, Lithium, scatter more compared to heavier elements, Manganese. The direction of the background gas influences the collision of Lithium and Manganese atoms with Argon atoms by reorienting the collision towards left or right. The optimized model deepens the insights on the collision dynamics and stoichiometry between plume and background gas as the factor of direction is included.
