The achievement was developed within research field (1) Optodynamic aspects of light-matter interaction. We have developed the theoretical description and experimental approaches for studying the most basic aspects of different optodynamic interactions. In this context, we examined the motion of matter occurring due to the transfer of the conservational physical quantities (energy, linear and angular momentum) from light to matter. By the modeling as well as the design and implementation of several basic experiments, we confirmed the theoretical models and investigated different examples of the electrodynamics of laser-pulsed optical manipulation, including the generation of elastic waves in the confined ablation and in the radiation pressure regime. The obtained results represent a significant milestone in understanding the different regimes of optodynamic interactions. The achievement represents an important step in understanding the transfer of different conservational physical quantities from light to matter. We expect that the results of this achievement have the potential to clarifying the century-old Abraham-Minkowski dilemma of the momentum of light in matter. Additionally, the results represent an important milestone in the further development of laser induced mass transfer and laser space propulsion. The achievement was presented at a scientific conference (EMN Light-Matter Interactions Meeting, Singapore) as an invited lecture and at several scientific international conferences. The main findings were presented also in several scientific papers.
