摘要：

X-ray production from the interaction of femtosecond laser pulses focused to relativistic intensity into re-entrant targets etched into silicon has been investigated. K-alpha and hard x-ray yields were compared when the laser was focused into pyramidal shaped cone targets and wedge shaped targets. Hot electron production is highest in the wedge targets irradiated with transverse polarization, though K-alpha is maximized with wedge targets and parallel polarization. These results are explained with particle-in-cell simulations. (c) 2008 American Institute of Physics.
