En focalisant le faisceau d'un laser (P = 1010 W ; Ɗt = 3,7 ns) sur une cible de deutérium solide, on crée un plasma suffisamment chaud pour engendrer des réactions nucléaires de fusion. On observe et on étudie, expérimentalement, la réflexion d'une partie de l'énergie laser par le plasma ainsi que la variation du nombre de neutrons avec l'énergie laser (variable entre 20 et 80 J).A powerful laser beam (P = 1010 W ; Ɗt = 3.7 nsec) is focused on a solid deuterium stick. The such laser-produced plasma is hot enough to create nuclear fusion reactions. We give experimental data upon reflection energy measurements and scaling law of neutron fluxes versus 20 - 80 J incident energy
