Abstract:In laser-ion acceleration experiments, the interaction of the rising flank of a high power laser pulse with the target can cause pre-ionization and subsequent target pre-expansion long before the arrival of the main laser peak. Exact knowledge of this target pre-expansion is required in order to understand the laser-plasma acceleration mechanisms with the help of numerical simulations.
For dielectric targets, the starting point of target pre-expansion is characterized by the point in time at which the … Show more
