摘要: The triple probe technique has been used to study the parameters of flowing plasma plume formed by laser-blow-off (LBO) a multicomponent LiF–C target. advantages Langmuir over single have discussed with regard present study. Our results show that is better suited for parametric measurements close spatiotemporal evolutions electron density and temperature were measured in different ambient environments various laser fluences. angular distribution was also measured. It found presence gas drastically affects LBO plume. Large enhancement ne Te at intermediate pressures (10−2 Torr) expected due increase collisional processes. On other hand, fluence does not affect observed significantly. In vacuum, new phenomenon, i.e., an oscillation trailing portion plum...
