      abstract     = {The conversion efficiency of a 90 fs high-power laser pulse
                      focused onto a solid target into x-ray Kalpha line emission
                      was measured. By using three different elements as target
                      material (Si, Ti, and Co), interesting candidates for fast
                      x-ray diffraction applications were selected. The Kalpha
                      output was measured with toroidally bent crystal
                      monochromators combined with a GaAsP Schottky diode.
                      Optimization was performed for different laser intensities
                      as well as for different density scale lengths of a
                      preformed plasma. These different scale lengths were
                      realized by prepulses of different intensities and delay
                      times with respect to the main pulse. Whereas the Kalpha
                      yield varied by a factor of 1.8 for different laser
                      intensities, the variation of the density scale length could
                      provide a gain factor up to 4.6 for the Kalpha output.},
