When the end of the electric field vector travels in an ellipse, the light is elliptically polarized.

电场矢量的末端沿一椭圆移动的光叫椭圆偏振光。

Comparing with FWM without dressing fields (NDFWM), the strength of the singly-dressing FWM (SDFWM) signal is suppressed when the modulation-field is linear or elliptically polarized.

与非缀饰四波混频(NDFWM)信号的强度相比，单缀饰光作用下的四波混频信号(SDFWM)的强度在偏振调制光为线偏振及椭圆偏振的情况下受到了不同程度的抑制。
