Laser fusion - high density compression experiment and ignition program with GEKKO XII

In this review, the high density compression of main fuel and the stable formation of a hot spark at the center of the imploded core were investigated to obtain the scaling and the requirements for fusion ignition and high gain. The experimental data of the high density compression up to 600 times solid density with hollow shell pellet were analyzed and compared with simulations. Recent progress of solid state laser technology with laser diode pumping has made the laser fusion scheme realistic for fusion energy development. A reactor driver with the specifications of an output energy of MJ/pulse, efficiency of 5-10%, short wavelength of 0.3-0.5 microns, repetition of 10-100 Hz with high controllability of pulse shape and focusing, has become feasible for design and construction. 50 refs., 42 figs., 1 tab
