"A focused high-power ns laser pulse impinging on a solid-state target generates on its surface an initial plasma sheet, with which the laser radiation interacts. The main objective of the proposed project is to study the spatial and temporal evolution of fast hydrodynamic processes in the initial phase of the laser-target interaction by means of the optical shadowgraphy technique using synchronized auxiliary fs laser pulse. One of the essential factors determining the course of the laser-target interaction is the intensity beam profile in the interaction plane. We are going, therefore, to simulate first the beam path through the whole optical system of the PALS laser by using the GLAD 5 software. The simulated beam profiles will be compared with the available experimental data and results obtained by the proposed fs shadowgraphy. The expected information will contribute to the search for methods of active control of the plasma corona evolution, which is crucial for example for plasma jet and fast ion streams generation, and also for realization of the direct-driven inertial fusion."@en .
