摘　　要：用斜入射方法并考虑了激光被折射和Ｐ极化激光的共振吸收，计算了碳纤维靶的等离子体状态和激光增益。激光斜入射获得的类Ｈ－碳的ｎ＝２、３跃迁的激光增益系数，比按垂直入射的计算的值略大，但是，增益系数的空间分布变得更窄。激光增益发生在更靠近靶的外表层。The plasma condition and the gain coefficient of a carbon fiber target,which is irradiated by oblique incident laser light were calculated. The refraction of laser and the resonance absorption of P polarization laser were considered. The gain coefficient value of H like C, n =2,3 comparing with vertical incident is higher,however the gain region becomes narrower and the gian region towards to the outer layer of the fiber target plasma.
