A general geometric condition, involving group velocities, for large bandwidth parametric amplification with all types of phase-matching and in certain wavelength ranges is derived. This condition has been exploited to produce visible widely tunable

It is demonstrated that the Hamiltonian responsible for the formation of Fermi-resonant two-vibron bound states can be uncoupled, leading to a description of the bound states analogous to that of pure molecular vibrations. In the case of relaxation o

Direct observation of temporally varying molecular geometries during a chemical reaction is very challenging. Ultrafast (pico- and femtosecond) laser spectroscopy allows the detection of various short living species and the determination of their lif

It is shown that time-resolved nonlinear optical techniques can be extended to the selective study of the dynamics of vibrational overtones and two-phonon states in condensed media. In a primary application the first experimental demonstration of coh
