Abstract

To improve the detection efficiency of electro-optic (EO) sampling of terahertz waves, we propose “polarization filtering,” where the main polarization component of the probe optical beam is suppressed after the interaction in the EO crystal. Experimentally, we achieved a factor of 2.4 increase in the EO sampling signal by the polarization filtering.

偏振滤波对太赫兹EO采样信号的增强

为了提高太赫兹电光(EO)采样的检测效率，我们提出了“极化滤波”，即探针光束的主要偏振分量在EO晶体中相互作用后被抑制。实验结果表明，极化滤波后的EO采样信号提高了2.4倍。
