  For developing a laser boron fusion reactor driven by picosecond laser pulses
of more than 30 petawatts power, advances are reported about computations for
the plasma block generation by the dielectric explosion of the interaction.
Further results are about the direct drive ignition mechanism by a single laser
pulse without the problems of spherical irradiation. For the sufficiently large
stopping lengths of the generated alpha particles in the plasma results from
other projects can be used.
