A laser driven fusion method in which a sphere of fusion fuel is compressed indirectly by X-rays generated after the lasers hit the inner wall of the metal cavity. The target, a sphere containing frozen hydrogen, is suspended on plastic filaments inside a metal cylinder called a hohlraum. Powerful laser beams aim through holes in the ends of the cylinder at its inner wall. It starts to emit powerful X-rays that fills uniformly the whole cavity. The radiation pressure then compresses the target to the levels needed for thermonuclear fusion. The indirect-drive approach provides more uniform compression of the target surface while having lower requirements for precise laser targeting.
