This paper reviews the important schemes that have been investigated thus far in fast ignition research. Integral experiments for fast ignition research have been conducted utilizing various schemes: (a) double-pulse experiments with two 100-ps pulses injected to a compressed core, (b) gold cone-guided implosion with 100-TW laser pulse heating, and (c) imploded core heated by both a 100-TW and petawatt laser pulses through gold cones. Reviewing these results, several important issues were raised for further development of fast ignition research. The imploded core heated by a petawatt laser through a gold cone showed a 103 D-D neutron increase compared to the one with only the CD shell implosion.
