In viewing significant progresses in technical achievement toward a high-intensity neutron source driven
by a high-power laser came up with the high power laser development, we have reviewed the currently
most advanced moderator system and neutron optics, which are the key elements for the neutron beam
applications. Regarding the moderators, concepts adopted in J-PARC pulsed neutron source, which is
one of most advanced system, were described to give a baseline design. Also a new to direction of
moderator concept is shown, which could be a high brightness candidate for the high-intensity laser
driven system. On the neutron optics, the most fundamental consideration is primarily reviewed along
with recent progress in new devises for enrichment of neutron-beam characteristics.
