Аннотация: We demonstrate a new modality of ultrafast laser spectroscopy based on high-harmonic-driven stimulated Raman scattering (hi-SRS) and incoherent laser-plasma emission (iLPE). The spectra of high-order harmonics driven by sub-100-fs pulses in the mid-infrared are shown to display well-resolved Raman-gain, Raman-loss, and iLPE features, enabling a chemically specific, single-beam, single-shot spectroscopy of gases and plasmas within a spectral range stretching from the near-infrared to vacuum ultraviolet. We present a theoretical framework based on a suitably adapted nonlinear evolution equation that enables a closed-form description of hi-SRS as an ultrafast nonlinear-optical phenomenon. We show that the content of hi-SRS as a physical process and as a method of spectroscopy goes well beyond standard SRS, offering a powerful resource for spectroscopy, remote sensing, and ultrafast optical science. Standing out as particularly relevant for nitrogen-containing gas systems, including atmospheric air, is a multimodal spectroscopic probe that combines ultrafast hi-SRS via the second positive system of molecular nitrogen with iLPE via the γ band of nitrogen monoxide.
