Laser-driven neutron sources offer a unique characteristic as a brightness neutron source because they
provide a short pulse duration (less than ns) in time and a small spot size (a few mm2) in space at the
source point. The peak flux per driver energy reaches 1017 n/cm2/s/J, which is 1,000 times higher than
that achieved by an accelerator-driven source. We compared the characteristics of a laser-driven neutron
source with those achieved by an accelerator-driven source by focusing on the amount of neutron
production numbers on the source as a function of driver energy. We also present the technological
status or perspective of laser-driven neutron sources in order to achieve an average production rate
1011 n/sr/sec that obtained by a compact accelerator-driven neutron source.
