Description

A brief overview of ion emission results obtained in interaction experiments performed with short-wavelength laser pulses of a duration ranging from tens of femtoseconds to tens of nanoseconds will be presented. We compare the basic characteristics of ion emission generated by ultrashort pulses delivered by soft x-ray (FLASH2) and x-ray (European XFEL) free-electron lasers. For further comparison, short pulses from plasma-based XUV/UV lasers provide information on interactions that can no longer be considered isochoric. Finally, we will deal with isotope effects and cascade phenomena that occur during the emission of ions from a plasma generated by a focused beam of short-wavelength laser radiation.
