我们描述了发射和检测超短太赫兹电磁脉冲的大孔径平面光电导天线的功率缩放和饱和特性。在高光通量下，辐射电场在与偏置场相当的值处饱和，这与辐射机制的简单模型一致。
We describe the power scaling and saturation properties of large‐aperture planar photoconducting antennas which emit and detect ultrashort terahertz electromagnetic pulses. At high optical fluences, the radiated electric field saturates at a value comparable to the bias field in agreement with a simple model of the radiation mechanism.
