    Laser-induced spectral broadening and hole-burning in rare earth doped crystals and coherent optical spectroscopy for frequency upconversion

    The excitation spectra for linear fluorescence and for frequency upconversion are recorded in Er3+ doped crystal Er:YAG. An excitation induced spectral broadening and hole-burning are shown to appear at the reson...

    Quantum chemical construction of a reduced reaction Hamiltonian and T 1 -relaxation and pure T 2 -dephasing rates for the proton transfer in 3-chlorotropolone

    Separating multidimensional problems into that of a relevant system which is coupled to a bath of harmonic oscillators is a common concept in condensed phase theory. Focusing on the specific problem of intramo...

    Femtosecond Optical Spectroscopies of Solvated Polyatomic Molecules

    A multimode Brownian oscillator model is developed for third order nonlinear optical spectroscopies in condensed phases, taking into account molecular dynamics of coherent nuclear motions of the absorber and t...
