Pulsed Two-Dimensional Atomic Crystal Cavity Optomechanics

Molecular cavity optomechanics is a new description of surface enhanced Raman scattering, and in return, surface enhanced Raman spectroscopy provides a new method for constructing and studying high coupling strength cavity optomechanics system. Moreover, pulsed excitation with duration time shorter than the phonon decay time, along with two-dimensional atomic crystals with well-defined arrangement and lattice orientation, facilitates the quantitation and simultaneously resolution of the time scale and the space scale. Here we show some results based on such a platform.
