Abstract
The measurements of Badziak et al with very clean - i.e. with a contrast ratio above 10 - TW-ps laser pulses demonstrated that relativistic self-focusing was avoided and the conditions of plane wave geometry could be applied to produce a skin layer interaction process [1] in full agreement with the experiments with the consistence of a dielectric swelling of 3.5. The experiments confirmed that the emitted ion blocks driven by the nonlinear force against and with the laser beam showed the concluded 10 A/cm2 moving within narrow cones [2] in contrast to all the cases with relativistic self-focusing. We report how the limit of 10 J/cm2 energy density can be lowered by up to a factor 50 if collective effects, anomalous resistivity and particle interpenetration are included such that the laser driven plasma block as a kind of light ion beam driver may induce a reaction solid state DT where 10 kJ-ps laser pulses may produce 100 MJ fusion energy. After the use for controlled fusion was clarified and any other use was excluded by a declassification procedure, this permitted first publications [3]. As a consequence of this, we report about the possibilities for a fast ignitor-like fusion power scheme where solid DT fuel may be used without compression.
