Query: A spectrally bright wavelength-switchable vacuum ultraviolet source
  driven by quantum coherence in strong-field-ionized molecules   We report generation of spectrally bright vacuum ultraviolet (VUV) and deep
UV (DUV) coherent radiations driven by quantum coherence in tunnel-ionized
carbon monoxide (CO) molecules. Our technique allows us to switch between
multiple wavelengths provided by the abundant energy levels of molecular ions.
The DUV/VUV sources can have arbitrary polarization states by manipulating the
pump laser polarization. The superior temporal and spectral properties of the
developed source give rise to a broadband Raman comb in the DUV/VUV region.
