Fig. 1: Schematic ignition target, the DD laser power (red) and radiation temperature Tr converted by the ID laser (black).

a The spherical hohlraum with an inner radius of 5 mm has 8 LEHs of each radius of about 1.6 mm and the ID laser (blue) and DD laser (purple) enter the hohlraum from LEHs, where the incident lasers are plotted schematically only in one of LEHs. The capsule is put in the center of the hohlraum. The critical surface is plotted by the dashed line and ΔRID between the critical surface and radiation ablation front (radiation ablation front) is the yellow region. b The layered DT fuel capsule structure and sizes. c Radiation temperature Tr (black) is converted by ID laser on the high-Z inner wall of the spherical hohlraum, and DD laser power (red) vs time.
