Broadband Terahertz Spectroscopy

Abstract

Terahertz (THz) spectroscopy is a non-contact technique to probe properties and dynamics of molecules and materials in the meV energy range and picosecond timescales. This chapter describes different popular methods of generation and detection of broadband THz pulses, experimental technique, and data analysis procedures of THz time-domain and time-resolved THz spectroscopy. We have also reviewed some recent representative works utilizing these methods.
