我们测量和计算了太赫兹(THz)探测效率随太赫兹极化与晶体(001)轴夹角的变化关系。我们发现，对于探头和THz极化之间的0度和90度角，THz检测过程是最有效的，而通常使用的45度角给出的结果不是最优的。此外，我们还说明了在已知晶体(001)轴方向的情况下，如何确定太赫兹光束的偏振方向。我们的结果适用于闪锌矿和其他闪锌矿晶体，如GaP。(C)2001年美国光学学会。
We have performed measurements and calculations of the efficiency of terahertz (THz) detection in ZnTe as functions of the angle between the THz polarization and the crystal (001) axis of the angle between the THz polarization and the probe-beam polarization. We find that, for angles of 0 degrees and 90 degrees between the probe and THz polarization, the THz detection process is most efficient, whereas the commonly used angle of 45 degrees gives less than optimal results. In addition, we show how the polarization direction of a THz beam can be found if the direction of the crystal (001) axis is known. Our results are valid for ZnTe and other zinc-blende crystals such as GaP. (C) 2001 Optical Society of America.
