  1. 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

    計算之後,我們給出太赫茲輻射與四波混頻信號關于lorentz局域場因子l的表達式,發現負時間延遲時在2k _ 2 ? k _ 1方向仍有四波混頻信號,其頻率也有所改變。
  2. At the same time the temperature coefficient of a dr could be positive or negative, and this may be used to compensate for the frequency drift due to temperature shift

    同時, dr的諧振頻率溫度系數可正可負,這可以大大提高dro的頻率溫漂性能。
