The generation and detection of short pulses of terahertz (THz) frequency electromagnetic radiation are attracting great interest. Research activities in this area are driven by applications of THz-frequency radiation pulses in time-domain THz spectroscopy and time-domain THz imaging.1,2 Recent examples of major scientic advancements in THz wave research include the detection of single-base pair differences in femtomolar concentrations of DNA,3 the observation of the temporal evolution of exciton formation in semiconductors4 and understanding of carrier dynamics in high-temperature superconductors.5 Real-world applications of time-domain THz spectroscopy and imaging address important problems such as nondestructive testing,6 as well as new approaches to medical diagnostics and rapid screening in drug development.7
