Abstract
High-density implosion of fuel targets for laser-driven inertial confinement fusion has been intensively studied for many years. High temperature and high density of the imploded core plasmas up to 10 keV and 600 g/cm3, respectively were achieved successfully. Then, hydrodynamically equivelent plasma (HEP) with central spark/main fuel structure has been demonstrated for central spark ignition scheme. On the other way, implosion for fast ignition scheme, particularly nonuniform implosion of target with cone for entrance of heating laser, has recently been studied. Thermonuclear ignition and burn of inertial confinement fusion by laser are expected to take place near the year 2010.
