Observation of soft x rays from a tungsten plasma produced by intense subpicosecond laser pulses is reported. X radiation of several keV photon energy was observed with just a few millijoules of laser energy. Using two consecutive pulses for the generation of the plasma the x-ray emission is maximal for a delay of about 30 to 50 ps between the laser pulses.
