Femtosecond lasers have in recent years been shown to be space qualified and with the development of compact femtosecond laser systems [1,2], Terahertz Time-Domain Spectroscopy (THz TDS) allows meanwhile to cover an essential part of the molecular fingerprint spectral range and has several technological advantages over the commonly used Fourier-Transform Infrared techniques (FTIR). The advantages are compactness, replacement of components (cryogenic) spectrally broadband infrared detectors with electro-optic/acousto-optic photonic techniques and the potential to be chip-integrable. Here we show our progress enroute to a THz time-domain spectroscopic setup for space applications with a bandwidth of over 30THz and a resolution of better than 100GHz [3].
