A high brightness, Raman amplified KrF laser has been used to irradiate solid targets with 12 ps laser pulses at intensities above 10[sup 15] W/cm[sup 2] without the presence of a preformed plasma caused by low level amplified spontaneous emission prepulse. Time-resolved x-ray spectroscopy of the [ital K]-shell emission from aluminum was used to infer electron densities in excess of 10[sup 23] cm[sup [minus]3] at temperatures of several hundred electronvolts.
