We present systematic investigations on the generation of titanium -radiation (E=4.5 ) from plasmas produced with ultrashort, high-intensity laser pulses. A maximum -yield appears at a laser intensity of about , corresponding to a plasma electron temperature of a few times the photon energy. We observe a second increase in the -emission yield at intensities higher than a few times 1018 , due to the increase in the K-shell ionization cross-section for relativistic electrons. The intensity dependence of the -yield is modeled by an analytical expression, only including cross-section, pathlength and electron energy distribution.
