Abstract :
It seemed to be an impossible task thirty years ago to shine a laser beam on uncompressed solid DT and to ignite a fusionflame since the necessary energy flux densities are in the range of more than 100MJ/cm2 or corresponding deuteriumion current densities above 1010 Amp/em which conditions were completely out of range. Since PW-ps laserpulses are available now, the situation has changed, however, by inclusion of a very sophisticated method for suppressingprepulses such that relativistic self-focusing is avoided and a purely plane or similar geometry interaction as a skinlayer process appears. Out of the wide stream of research, only very special experiments with clear laser pulses confirmedthis kind of interaction in theoretical and numerical agreement. This leads to the space-charge neutral plasmablocks or pistons generated by the nonlinear (ponderomotive) acceleration for producing the necessary ion current densitiesfor the optimized ion energies of 80 keV to irradiate solid state DT. While numerous further properties have to beevaluated, the aim seems to be attractive for the very low cost fusion energy production by laser irradiation
