NUCLEAR FUSION TARGET, NUCLEAR FUSION DEVICE, AND NUCLEAR FUSION METHOD

摘要

An object is to be capable of inducing a nuclear fusion reaction at a relatively high efficiency and downsize a device. A nuclear fusion device 1 of the present invention includes a nuclear fusion target 7 including a target substrate 7a containing deuterium or tritium and a thin-film layer 7b containing deuterium or tritium stacked on the target substrate 7a, a vacuum container 5 for storing the nuclear fusion target 7, and a laser unit 3 for irradiating two successive first and second pulsed laser lights P1, P2 toward the thin-film layer 7b of the nuclear fusion target 7, and the intensity of the first pulsed laser light P1 is set to a value that is smaller than that of the second pulsed laser light P2 and allows peeling of the thin-film layer 7b from the target substrate 7a.
