| 摘 要： | 研究了相对论效应引起的场量的非线性对谐波辐射源的影响；在入射光为长脉冲激光并计及各阶谐波间的耦合时，解析研究了三次谐波的振幅、频率、相位的变化及增长与饱和特性并计算了转化率，结果表明谐波间的耦合使幅值和转化率减少。

| Abstract: | The nonlinearity of laser field induced by relativistic effect and its influence and harmonic generation are investigated. The variations of amplitude, phase and efficiency of third harmonic content are analyzed by taling into account the coupling among harmonics of different orders, the growth and saturation of third harmonic wave are also described. Results show the coupling effect can decrease the amplitude and effciency of relativistic harmonic radiation for the long laser pulse limit. |
