Název v původním jazyce
Enhanced electron acceleration via ultra-intense laser interaction with structured targets
Popis výsledku v původním jazyce
The generation of energetic electrons by the interaction of a short laser pulse with solid "grating" targets, having a periodic groove on the irradiated surface, has been investigated in a regime of ultrahigh contrast (1012) and relativistically strong intensity (> 1019W/cm2). A strong enhancement of both the energy and number of electrons emitted from the target, with respect to at targets, has been observed for incidence angles close to the resonant condition for surface wave excitation. In particularwe identified bunches of electrons with energies exceeding 10 MeV which are emitted in a direction close to the target surface. The experimental results are well reproduced by a three-dimensional particle-in-cell simulation, which confirms the dominantrole of the surface wave in accelerating the electrons. These results are a step forward the development of high field plasmonics for a number of applications.
