Abstract
Progresses and future prospect of laser fusion research and developments of tritium handling
techniques for laser fusion are reviewed. Implosion physics of laser fusion targets toward central ignition
has been intensively investigated for more than 30 yeays. Numerous milestones such as high density compression
and heating of fusion fuel habe been achived. Recently a new scheme named fast ignition is opened by the
development
of highly intensive laser technology. Both by the central ignition and the fast ignition schemes, fusion
ignition
and burn will be demonstrated in the near future. Since the early stage of laser fusion reserch, DT fuel has
been introduced
in the implosion experiments. Numerous techniques, such as DT gas filling over 1000 atmospheric pressure into
the glass and
plastic shell targets, formation of uniform cryogenic DT layer on the inner wall of shell target, cleaning of
target chamber wall
and recovery system of DT fuel after the experiments, and safety system to preclude accidental release of DT
gas and to minimize the potential
for exposures to personnel, have been developed.
