Terahertz quasi time domain spectroscopy
Optics Express, 2009 It is shown theoretically and experimentally that for the specific case of an equidistant frequency spacing of semiconductor laser modes, signals similar to terahertz (THz) time domain spectroscopy (TDS) can be detected in a standard photomixer setup.

Terahertz Time-Domain Spectroscopy [PDF]
Scientific Video Protocols, 2020 Time-Domain terahertz spectroscopy (THz TDS) has attracted attention from many scientific disciplines as it enables accessing the gap between electronic and optical techniques. One application is to probe spintronic dynamics in sub-picosecond time scale. Here, we discuss principles and technical aspects of a typical THz TDS setup.

Broadband circular polarization time-domain terahertz spectroscopy [PDF]
Physical Review Materials, 2020 Light-matter interactions are key in providing fundamental information about materials. Even in the linear-response regime, the spectroscopic response of a material encodes in it many properties of the ground state as well as of its excitations.
