Abstract

In contrast to laser fusion with spherical plasma compression to very high densities, the alternative was studied with side-on ignition of solid state (or modestly higher) deuterium-tritium, based on hydrodynamic theory. The extremely difficult conditions may be overcome using petawatt-picosecond (PW-ps) laser pulses, however, only by applying the advantages of a discovered anomaly of plane geometry interaction without relativistic self-focusing using very high contrast ratios of the laser. The conditions of this side-on ignition could be further relaxed by inclusion of interaction effects. Ignition of solid state density or modestly compressed deuterium-tritium (DT) and of proton-boron11 (HB11) seems to be possible with laser pulses of several PW power and ps duration.
