Hydrodynamics of laser accelerated foils Josin, Gary M.


A ruby laser system has been constructed and characterized to check the applicability of a diagnostic method which extracts all the hydrodynamic parameters without any knowledge of the microscopic physics. Our diagnostic method is not yet employable since strong shock waves are not generated with the available laser system. However the experimental results agree with a general heat wave model which is based on a universal heating characteristic. Furthermore the experimental results are consistent with the well documented Medusa hydrocode. It is of interest that for laser plasmas a universal heating characteristic exists from which the exhaust temperature for the laser plasma can be predicted from the laser intensity alone.
