Experiments that examine the interaction of high-intensity subpicosecond laser radiation ({approximately}10{sup 18} W/cm{sup 2}) with solid targets are performed. Soft-x-ray spectra from interactions with Teflon and aluminum targets that imply the creation of high-temperature ({approx_gt}200 eV) high-density ({approx_gt}10{sup 23} cm{sup {minus}3}) plasmas are obtained. Effects of a prepulse on the plasma characteristics are examined. The applicability of short, intense laser pulses for the formation of population inversions on x-ray transitions during recombination of high-density plasmas is discussed. {copyright} {ital 1996 Optical Society of America.}
