Recently, space-qualified femtosecond laser systems have become available [1,2]. Time-domain spectroscopy techniques, which revolutionised spectroscopy in laboratory environments, are now hence becoming true alternatives as modern spectroscopic sensors for space exploration. Bulky opto-mechanical components can thereby be replaced with compact electro-optic photonic components. Here, we show our progress enroute to time-domain spectroscopy instrumentation that is able to detect Raman- or infrared-active resonances in matter with a bandwidth of 30THz (1000 cm-1) and a resolution of 100GHz (3.3 cm-1).
