Prof. Lisyansky has published the article entitled “Enhancement of the Raman effect by infrared pumping,” in Phys. Rev. Lett. 122, 153905 (2019).

In this article,  we proposed a method that engenders coherent Raman scattering and enhances both Stokes and anti-Stokes Raman scattering from an ensemble of molecules by four orders of magnitude compared to incoherent Raman scattering by illuminating the sample with a coherent IR light at the half-frequency of the Stokes shift. The method produces coherent Stokes and anti-Stokes signals which amplitudes are about the same. Unlike coherent anti-Stokes Raman spectroscopy (CARS), this method allows for measuring both Stokes and anti-Stokes signals  and eliminates drawbacks of CARS such as the energy transition between the laser beams that leads to signal suppression and limits the sensitivity.
