Using x-rays of 60-200 keV photon energy lambda ranges 0.06 to 0.2 A as an ionizing radiation source in a transmission-line-driven, low-inductance discharge chamber, we have succeeded in generating spatially-homogeneous pulsed avalanche discharges of several liter volume at greater than 1 atm pressure for up to 100 nsec duration. In concurrent laser generation experiments with relatively lossy windows, we have observed high optical quality pulsed uv laser output of up to 2 Jliter from such discharges in rare gashalogen mixtures, and ir laser output of up to 12.5 Jliter from a HeN2CO2 mixture.
