| 摘 要： | 用紧致密度矩阵和弛豫时间近似方法，研究退极化效应对三次谐波产生的影响。给出三次谐波产生系数表达式。在半抛物量子阱中，给出三次谐波产生的数值结果。退极化效应破坏了三共振，修改了三次谐波产生谱。使原来的三共振峰退化为一双共振峰和一单共振峰。

| Abstract: | The influence of the depolarization effect on the third-harmonic generation spectrum in an asymmetric semi-parabolic quantum well is studied. A concise formulation of the thirdharmonic generation is presented. The calculation of a semi-parabolic quantum well shows that triply resonance is destroyed by the depolarization effect and original triply resonance peak is replaced by one double resonance and one single peak. |
