摘要
对短脉冲强激光在非稠密均匀等离子体中传播时产生的相对论相干谐波辐射进行了一般性研究．在准稳态近似（ｑｕａｓｉｓｔａｔｉｃａｐｐｒｏｘｉｍａｔｉｏｎ）下得出ｎ阶谐波包络的演化方程。
The characteristics of high order relativistic harmonic generation excited by intense laser pulse in underdense plasmas is inverestigated. With quasistatic approximation, the growth and saturation of N th order relativistic harmonics are analyzed, and the ratio of high order power to fundamental wave power is described and calculated.
