【Abstract】 Using pulse laser as probing source,holographic double exposure is applied to diagnose laser intertia restrain nuclear fusion high temperature and high density plasma.It is a new method to diagnose.The main laser and probing laser are strictly synchronism Δt≤10 -11 ～10 -10 s,plasma two dimension image of high spatial resolution Δδ≤1μm can be obtained.Time resolution Δt can reach 10 -11 s.Recording plasma refracting power spatial distribution is the foundation of measuring density section change and computing parameters of plasma fluid dynamics.更多还原
