Abstract
Implosions of a target pellet exposed to an intense laser light are investigated numerically by using the spherically symmetric hydrodynamic equations. In order to obtain the maximum output of the fusion energy from the pellet, the following facts are pointed out: (1) There is an optimum value for the laser intensity: (2) It is effective to replace the outside part of the critical density of the target plasma by a substance with a heavier particle mass: (3) For large pellets, a larger laser power is efficient: (4) There is an optimum shape for the laser pulse: (5) More output energy is yielded from a pellet with a larger radius when the power and the pulse shape of the laser light are optimum.Keywords
