The terahertz emission , which is a second - order response , and the four - wave mixing signal , a third response , are given the expressions related to the lorentz local field factor l . we found a four - wave mixing signal in the direction 2k2 - k1 for the negative time delay , and the frequency of the four - wave mixing signal has a shift related to the lorentz local field factor l
计算之后，我们给出太赫兹辐射与四波混频信号关于lorentz局域场因子l的表达式，发现负时间延迟时在2k _ 2 ? k _ 1方向仍有四波混频信号，其频率也有所改变。
