  ABSTRACT: This paper describes the study of implosion processes of glass microballoon targets irradiated directly and uniformly by the GEKKO XII glass laser system. In this direct driven mode using a high‐aspect‐ratio target, high neutron yields were achieved. Comparison between experiment and the computer simulation using one‐dimensional hydrodynamic codes shows good agreement. Progress of direct driven implosion shows the possibility of achieving breakeven by using the 100 kJ class laser of 0.35 μm wavelength.

  ABSTRACT: An analysis of the dynamic characteristics of parasitic oscillation between target and pinhole of a beam expander was carried out using a simplified rate equation model. Suppression of parasitic oscillation was also investigated in view of the oscillation dynamics. Useful results were obtained quantitatively concerning the rise time of the amplifier gain and the distance between the target and the final amplifier of the laser fusion system.
