摘要：

Soft x-ray spectra generated on flat Al targets by a 500 fs KrF* laser pulse (intensity 5.3 X 10(15) W/cm2), preceded by a prepulse of the same pulse duration, have been measured as a function of the pulse separation and the prepulse intensity. It was found that not only the total x-ray emission was much stronger when the prepulse was present but, in particular, lines in the shorter wavelength region had a higher intensity than without prepulse, and were strongly dependent on the time separation between the prepulse and the main pulse.
