"spatio-temporal hologram of molecular vibrations created in gas by stimulated Raman scattering... operates at pressure-tuneable wavelength, for quantum communications, where efficient sources of indistinguishable single-photons unavailable at wavelengths compatible with existing fiber networks... combines quantum optics, gas-based nonlinear optics, hollow-core PCF, and molecular vibrations... can operate in any spectral band"
