Description	High speed, well-collimated plasma jets were generated in the interaction of defocused single laser beam with Cu target. The experiment was carried out at the Prague Asterix Laser System - PALS using the third harmonic beam (0.438 mu m) with a pulse duration of 250 ps and an energy of 100 J. Plasma parameters were obtained by means of a 3-frame interferometric system. The plasma jet parameters reach the following values: the velocity up to 7x10(7) cm/s, the internal Mach number greater than 10 and the electron density above 10(19)cm(-3). The jet characteristics are appropriate for the astrophysical and ICF applications. A high-pressure supersonic gas nozzle was used for interaction of this jet with ambient gas. Effect of shocks formation in He and Ar due to the jet action is clearly visible.

(en) V pražském laserovém centru PALS byly generovány plasmové jety při interakci defokusovaného laserového svazku s Cu terčíkem. Byl použit svazek třetí harmonické (0.438 μm), délka pulsu 250 ps a energie 100 J. Parametry plasmatu byly získávány tříkanálovou interferometrií. Parametry jetu dosahovaly hodnot: Rychlost až 7.107 cm/s, Machovo číslo větší než 10 a elektronová hustota přes 1019 cm-3 . Charakteristiky jetu jsou vhodné i pro astrofyzikální modely nebo fúzní aplikace. Byla použita vysokotlaká nadzvuková tryska pro interakci jetů s okolním plynem. Efekt tvorby rázové vlny v He a Ar působením jety byl jasně pozorovatelný. (cs)
