摘要：
Experiments that examine the interaction of high-intensity subpicosecond laser radiation (∼1018W/cm2) with solid targets are performed. Soft-x-ray spectra from interactions with Teflon and aluminum targets that imply the creation of high-temperature (>200 eV) high-density (>1023cm-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. © 1996 Optical Society of America.
