Monochromatic, wide tunable terahertz-wave spectrometer working at room temperature

摘要

Using a surface-emitted THz parametric oscillator, an MgO:LiNbO3-based frequency up-conversion detector and a special optical design for fast frequency tuning and achromatic THz-wave detection, we realized a room-temperature-operated THz frequency-domain spectrometer (THz-FDS).
