Abstract

Laser ablation propulsion and hypervelocity impacts are developing areas of research. This work aims to understand the contribution of different laser and target parameters to the momentum transfer during laser ablation through ballistic pendulum experiments. The data presented are the results of three experimental campaigns using different pulse durations, wavelengths and energies. The momentum was calculated from Photonic Doppler Velocimetry (PDV) and pendulum deflection measurements, while the contribution of the ejecta was estimated by camera imaging. The experimental results were complemented by 1D simulations of the momentum and ejecta contribution using the ESTHER code.
