摘要：
We present a new method for broadband terahertz (THz) pulse detection by parametric process in a non-collinear phase matching geometry using a lithium niobate (LN) crystal. Counterintuitively, our results show the ability to spatially separate the broadband up-converted signal with a resolution of a few GHz. This striking result will have a significant impact for advanced sensing of THz light detection, whether for single-shot spectroscopy or for ultrafast information transmission in this frequency range.
