Four-color laser diagnostics for Z-pinch and laser-produced plasma

Z-pinch Discharge in Laser Produced Plasma

Z-pinch effects in a laser produced aluminium plasma were investigated with a relatively low current fast coaxial electrical discharge. The ion flux in the laser produced plasma (LPP) was monitored with a Langmuir ion probe and the line density was controlled by using an aperture to select the portion of the LPP which enters the discharge cell. The Zpinch dynamics were recorded using time-resol...

Diagnostics of laser-produced plasmas

Laser-produced plasmas are used for a variety of studies, relevant for both basic physics and applications, and are of course essential within the study of inertial confi nement approach to nuclear fusion. Because of this large interest, a large variety of diagnostics have been developed and are routinely used to unveil the physical processes at work during plasma process and laser-plasma inter...

Laser triggered Z-pinch broadband extreme ultraviolet source for metrology

Diagnostics for laser plasma EUV sources

A high repetition-rate laser plasma source, possessing distinct radiation and particle emission characteristics, is now a principal candidate light source for the next generation of technology for the fabrication of computer chips. For these sources to satisfy this critical need they will need to meet unprecedented levels of performance, stability and lifetime. We review here some of the princi...

Laser-produced plasma-wall interaction

Jets of laser–generated plasma represent a flexible and well-defined model environment for investigation of plasma interactions with solid surfaces (walls). The pilot experiments carried out on the iodine laser system (5–200 J, 0.44 mm, 0.25–0.3 ns, ,1 10 W/cm) at the PALS Research Centre in Prague are reported. Modification of macroscopic characteristics of the Al plasma jets produced at laser...
