Fast ignition fusion requires transporting a large amount of energy into the compressed ICF capsule in a short period of time. One metthod for efficiently transporting laser energy into a compressed fusion capsule is to use a cone situated near or in the capsule, decreasing the distance to the core, improing laser conversion efficiency and concentrating charged particle flow. Results from recent experiments performed at the LANL 200 TW Trident short-pulse laser at ~10²⁰ W/cm² (80-100 J and ~600 fs) are presented.
