Abstract
High-energy ion emission from intense-ultrashort (30fs) laser-pulse-cooled deuterium-cluster (80K) interaction is measured. The deuterium ions have an average energy 20keV, which greatly exceeds Zweiback's expectation Phys. Rev. Lett. 84 (2000) 2634. These fast deuterium ions can be used to drive fusion and have a broad prospect.
