The role of the optical magnetic field is generally not considered at nonrelativistic light intensities. Here the authors show magneto-electric rectification, an optical nonlinear effect due to electric and magnetic field coupling, in a thin film of

Macromonomers [RPhSiO1.5]8,10,12 and [RCH═CHSiO1.5]8,10,12, where R is a conjugated group, have previously been shown to offer photophysical properties wherein excitation promotes an electron from ...
Probing solvent dependent femtosecond transient coherent oscillations to reveal interfacial dynamics

Journal of Optics. 24:063001
Probing transient states in molecules having vibronic transitions with femtosecond (fs) laser pulses often results in coherent oscillations either in the ground state, the excited states, or both. We find such coherent oscillations are highly solvent

The subject of electromagnetism has often been called electrodynamics to emphasize the dominance of the electric field in dynamic light–matter interactions that take place under non-relativistic conditions. Here we show experimentally that the ofte

We report induced second harmonic generation mediated by a new rectification nonlinearity in polycrystalline pentacene. Results with tilted pulse fronts confirm its magnetoelectric origin, ultrafast character and capability of supporting all-optical

We present ultrafast-depopulation-dynamics of higher-lying-excited-states using femtosecond fluorescence up-conversion techniques for two near-infrared (NIR) tricarbocyanine dyes (IR144 and IR140) in primary alcohols. With visible excitation waveleng

Cross-polarized light scattering in silsesquioxane (SSQ) molecules probes the azimuthal variation of intramolecular potentials. SSQ molecules with small and large cage interiors reveal variations in the sphericity of orbital shapes for the first time

We report harmonic generation mediated by magneto-electric charge separation in pentacene and optically-induced magnetization in a series of liquid tetrahalides for the first time.
