| 摘 要： | 分析了自生磁场对相对论谐波辐射的影响，得出结论，自生磁场对强激光在欠稠密等离子 产生的相对论相干波辐射有重要作用，自生磁场激发偶次谐波辐射，并对奇次谐波辐射产生影响，对二次，三次谐波作了详细分析，发现，自生磁场激发二次谐波辐射，而对三次谐波辐射有削弱作用，并且它还使谐波的失相时间延长。

| Abstract: | The effect of self generated magnetic field on relativisic harmonic generation is analysed. Results show that the self generated magnetic field excites even harmonics and influences the odd harmonics. Elaborate analysis of the second and the third harmonic generation shows that the self generated magnetic field excites second harmonic radiation, weakens third harmonic ratiation, and prolongs dephasing time of them. |
