Abstract :
Summary form only given. The high-resolved X-ray spectra resulting from the interaction of argon gas clusters with short-pulse laser radiation was studied. The cluster target was formed by the adiabatic expansion in vacuum of an argon gas puff produced by a pulsed valve with a conical nozzle. The gas jet was characterized by interferometry. The density profile has a Gaussian shape with a 4 mm width (at 1/e), and the peak density is 4.6/spl times/10/sup 18/ cm/sup -3/ for a maximum gas backing pressure of 15 bars. The experiments were carried out using the UHI10 laser. It is a two-beam 10 Hz Ti:sapphire system (/spl lambda/=800 nm). In our particular experiments the main beam has a 7 TW peak power.
