Abstract
A fuel pellet device for a fusion reaction. The fuel pellet including a core region comprises a fuel material, an ablator material configured surrounding the core region and an intermediary material comprising a metal material configured to absorb a laser light beam and generate an x-ray. The pellet also has a material comprising a structure overlying the intermediary material and configured to allow laser light pass and reflect any generated x-ray from the intermediary material toward the core region to ignite a fusion reaction.

A fuel pellet device for a fusion reaction, the device comprising:
- a core region comprising a fuel material;
- an ablator material surrounding the core region;
- an intermediary material comprising a metal material configured to absorb a laser light beam and generate an X-ray;
- and
- a structure overlying the intermediary material comprising a first dielectric distributed Bragg Reflector (DBR) comprising a plurality of periods numbered from 2 to 20, the structure being configured to allow laser light to pass, and reflect any generated X-ray from the intermediary material toward the core region.

A fuel pellet device for a fusion reaction, the device comprising:
- a core region comprising a fuel material;
- a plastic ablator comprising a carbon hydrogen material surrounding the core region;
- an intermediary material comprising a metal material configured to absorb a laser light beam incident on the fuel pellet device and generate an x-ray;
- an exterior material overlying the intermediary material, the exterior material comprising a glass or ceramic configured to absorb less than 1% of both laser light incident on the fuel pellet and the generated x-ray;
- and
- an external filter structure overlying the exterior material, the filter structure configured to allow laser light incident on the pellet to pass therethrough, and to reflect the generated x-ray from the intermediary material toward the core region.
