摘　　要：强激光（≈１０８－１０９Ｗ·ｃｍ－２）轰击固体靶产生等离子体，用４ｋＶ电势引出，得到最高总束流峰值为４．５ｍＡ，观察到离子最高电荷态为Ｃ３＋，Ａｌ３＋，Ｃｕ４＋，Ｔａ５＋，Ｐｂ４＋。另外，还详细研究了激光参数对等离子体的影响及激光等离子体的损失。A plasma has been produced with a solid target bombarded by a laser beam of high power (≈106-109W·cm-2). The total peak current of 4.5mA was obtained when 4kV of extracting potential was applied. The ions C3+,Al3+,Cu4+,Ta5+,Pb4+ were detected. In addition,the influence of laser parameters on the plasma and the loss of laser induced plasma are discussed in detail.
