Two static-electric-field-induced effects on harmonic generation are demonstrated analytically and numerically: elliptic dichroism (in which the harmonic yield is different for right and left elliptically polarized laser fields) and elliptical polarization of harmonics produced by linearly polarized driving laser fields. Both effects stem from interference of real and imaginary parts of the nonlinear atomic susceptibilities. Possibilities for experimentally measuring these effects are discussed.
椭圆二色性（其中对于右旋和左旋椭圆偏振激光场，谐波产率不同）以及由线偏振驱动激光场产生的谐波的椭圆偏振。这两种效应均源于非线性原子极化率实部和虚部的干涉。文中讨论了实验测量这些效应的可能性。
