摘要
Compact terahertz spectrometer. The spectrometer includes an optical beam both for generating terahertz radiation for interaction with the sample and for use in a detector. A DC heterodyne detector uses a DC field-induced second harmonic wave at a sensor plasma to serve as a local oscillator. The spectrometer has a bandwidth orders of magnitude larger than conventional THz spectrometers.
