Abstract

In this work we demonstrate a soft x-ray laser with neon- like argon ions using a gas puff target irradiated with a combination of long 600 ps and short 6 ps high-power laser pulses with a total of 10 J energy. The gas puff target was formed by pulsed injection of gas from a high-pressure solenoid valve through a nozzle in the form of a narrow slit. The target was irradiated in a traveling-wave excitation geometry. Lasing was observed on the 3p ¹S₀ implies 3s ¹P₁ transition at 46.9 nm and the 3d ¹P₁ implies 3p ¹P₁ transition at 45.1 nm. Gain of 11 cm^-1 was measured on these transitions for targets up to 0.9 cm long.
