Paper Abstract

Cryogenic liquid jets of either nitrogen or argon of up to 30 micrometer in diameter were exposed to intense laser fields with pulse durations between 70 fs and 3 ns leading to intensities of 1016 W cm-2 and 1013 W cm-2, respectively. The emission of extreme UV light and soft X-rays investigated by means of an absolutely calibrated soft X-ray spectrograph shows the characteristic lines of highly ionized nitrogen and argon atoms. For nitrogen the emitted photon flux at the longer pulse length was several orders of magnitude higher than for 70 fs pulses whereas for argon pulse durations around one ps lead to the highest conversion efficiency (CE) from laser to soft X-ray radiation.
