Abstract

Broadband terahertz (THz) radiation from laser-plasma interaction and a corresponding broadband THz time domain spectroscopy based on optically-air-biased-coherent-detection technique are presented. One of the single-shot detection techniques for THz time domain spectroscopy, the spectral-encoding technique, is also reviewed [1]. Distortions of the signals measured by this technique and the corresponding strategies to reduce them are demonstrated [2].
