Abstract

We have performed short-pulse laser-irradiated gas puff target experiments to generate a neonlike argon soft-x-ray laser by using a small laser system. A high-pressure solenoid valve forms a gas column through a narrow slit that is irradiated by two laser pulses containing 10 J of energy. Strong lasing is observed on two transitions, the $3p{ }^1{S}_0\to 3s{ }^1{P}_1$ line at 46.9 nm and the $3d{ }^1{P}_1\to 3p{ }^1{P}_1$ line at 45.1 nm. We present results from a systematic study in which the gas puff and laser conditions were varied to optimize the x-ray-laser output from a 0.9-cm-long gas column.
