To explore the lasting kinetics of UV-preionized, self-sustained discharge-pumped atomic xenon (5{ital d} {r arrow} 6{ital p}) lasers, the time-resolved spectroscopy of the laser output from the multiline laser resonator is reported. The diluents used are Ar and He. With the Ar diluent, the 1.73 {mu}m line occupied more than 90% of the total laser output energy, which can therefore characterize the total output performance. Increasing Xe concentration shortened the 1.73 {mu}m laser pulse duration and decreased the total (multiline) laser output energy, because increased Xe metastable state population contributes to the increase of the 6{ital p} state population (lower laser level) by electron-impact excitation and radiation trapping during discharge pumping. High-excitation-rate pumping resulted in the decrease of the laser output power of 1.73 and 2.63 {mu}m lines. Increasing the total gas-pressure leads to the high-efficiency operation due to the modest-excitation-rate pumping at high pressures. When the Ar diluent is partially replaced by the He diluent, the spectral line distribution is also discussed in terms of the relevant kinetic process.
