Paper Abstract

Nonlinear optics in a liquid hydrogen droplet is discussed. We carry out the stimulated Raman scattering (SRS) experiments using high-Q whispering gallery modes. We show that the liquid hydrogen droplet readily leads to high cavity Q-values exceeding 109 from ultraviolet to visible wavelength region. Using the high-Q liquid-hydrogen droplet, we demonstrate that, by pumping with an ultraviolet laser radiation, the SRS generates multiorder SRS sideband series through vibrational and rotational coherences covering whole ultraviolet-visible region from 200 nm to 900 nm, which may turn out as a super wideband optical comb generator. We also show that the SRS in the liquid hydrogen droplet proceeds for continuous operation with multiorder sidebands.
