Short pulse laser interaction with micro-structured targets: simulations of laser absorption and ion acceleration
The interaction of an ultrashort intense laser pulse with thin foil targets is accompanied by the acceleration of ions from the target surface. To make this ion source suitable for application, it is of particular importance to increase the efficiency of laser energy transformation into accelerated ions and the maximum ion energy. This can be achieved by using a thin foil target with a microsco...
متن کاملEnhanced proton acceleration by an ultrashort laser interaction with structured dynamic plasma targets.
We experimentally demonstrate a notably enhanced acceleration of protons to high energy by relatively modest ultrashort laser pulses and structured dynamical plasma targets. Realized by special deposition of snow targets on sapphire substrates and using carefully planned prepulses, high proton yields emitted in a narrow solid angle with energy above 21 MeV were detected from a 5 TW laser. Our s...
متن کاملHydrodynamic Aspects of Selenium X-ray Laser Targets
Recent experiments at KMS have been performed to investigate parameter variations of target component thickness, laser pulse duration and intensity, and one-sided vs two-sided irradiation in order to optimize the performance of the Livermore exploding foil selenium x-ray laser experiments. Preliminary experiments with selenium double foil targets were also conducted as a means of prolonging the...
متن کاملMicro-swimmers with hydrodynamic interactions
The low-Reynolds number motions of Purcell’s three-link swimmer, and of a closely-related two-paddle swimmer, are investigated and compared using slender-body theory and resistive-force theory. The results are compared (in the case of the three-link swimmer) with the resistive-force calculations of Becker, Koehler and Stone (BKS). In particular, we examine the effect of hydrodynamic interaction...
متن کاملExperimental characterization of picosecond laser interaction with solid targets.
We have characterized the plasma produced by a picosecond laser pulse using x-ray spectroscopy. High-resolution high-sensitivity spectra of K -shell emission from a Ti plasma have been obtained, showing a strong contribution from multiply ionized ions. Hydrodynamic and collisional-radiative codes are used to extract the plasma temperature and density from these measurements. We show that our me...
