Abstract :
We report the first demonstration of millijoule-level pulses and milliwatt average power from a table-top soft X-ray laser. Laser pulses with energy up to 1 mJ were generated at a wavelength of 46.9 nm by single pass amplification in a 34.5 cm long Ne-like Ar capillary discharge plasma. The large gain-length product of this plasma column allows for soft X-ray amplification in a highly saturated regime, resulting in very efficient energy extraction
