DIVS enables THz–fingerprint Raman spectra (grey trace) at an ultrafast real-time spectral acquisition rate of 24,000 spectra/sec. The key novelty of the method is the simultaneous detection of two complementary Raman signals: SE-ISRS (THz region-sensitive, blue trace) and FT-CARS (fingerprint region-sensitive, green trace).
