摘　　要：研究了作用在靶介质上的斜入射泵浦激光，对产生的靶等离子体状态以及激光增益区的影响。研究结果表明，等离子体状态和激光增益区随入射角θ０变化而变化。当θ０≤２０°时这种变化不大。当θ０约３０°时等离子体状态和激光增益区有比较明显的变化。当θ０≥４０°时，状态有很大的变化，严重影响激光增益和放大。The plasma state and the gain region produced by the oblique incidence laser on Ge target are studied and are compared with that produced by the vertical one.As a result of study,the absorption efficiency of the pumping energy turns far smaller ,the plasma state changes remarkable and the gain region becomes much narrower when incident angle is greater than 30°.
