    Low frequency lattice mode dynamics of cyclotrimethylene trinitramine (RDX) crystal studied by femtosecond time-resolved impulsive stimulated Raman scattering

    The femtosecond time-resolved impulsive stimulated Raman scattering (fs-ISRS) has been performed to study the low frequency lattice mode dynamics of the RDX crystal. Through Fourier filtering, four lattice mod...

    Coherent coupling of vibrational states in the MEH-PPV film investigated through Multi-Color Photon Echo

    The poly-[2-methoxy, (5-2′-ethyl-hexyloxy)-p-phenylene vinylene] (MEH-PPV) film is investigated by means of the Multi-Color Photon Echo (MCPE) technique. Under the three-order nonlinear response theory, the re...
