Experimental Observation of Ion Correlation in a Dense Laser-Produced Plasma

Hollow Ion Spectra In Warm Dense Laser-Produced Plasma: Observation And Modeling

X-Ray emission plasma spectra are investigated for 2 cases: i) plasma obtained under irradiation of Ar clusters by ultrashort laser pulses and ii) Mg-plasma heated by a short-wavelength long (nanosecond) laser pulse. It is demonstrated that under some experimental conditions very complicated spectra structures appear. Calculations in support of these measurements have been performed using a det...

Observation of laser satellites in a plasma produced by a femtosecond laser pulse

Ion characteristics of laser-produced plasma using a pair of collinear femtosecond laser pulses

Femtosecond laser-pulse absorption is studied in silicon ablation plasmas by means of a pair of identical 10 W/cm collinear pulses separated on a picosecond time scale. The second laser-pulse modifies ionic characteristics of the preformed plasma, such as ion yield, ion energy, and average charge state. Resonance absorption is demonstrated to be the dominant mechanism by comparing results of s ...

Direct observation of turbulent magnetic fields in hot, dense laser produced plasmas.

Turbulence in fluids is a ubiquitous, fascinating, and complex natural phenomenon that is not yet fully understood. Unraveling turbulence in high density, high temperature plasmas is an even bigger challenge because of the importance of electromagnetic forces and the typically violent environments. Fascinating and novel behavior of hot dense matter has so far been only indirectly inferred becau...

Hollow ion formation and line shape analysis in dense laser produced plasmas

X-ray emission from hollow ions is a fascinating field of research for many different branches like, e.g., nuclear physics (interaction of heavy ion beams with matter), atomic physics (atomic structure investigations, correlation effects of multi-electron systems, autoionizing channels of configurations with multiple excited electrons). Moreover, hollow ion configurations and the corresponding ...
