Abstract

We used the polarization-resolved beam-deflection technique to separate the bound-electronic and molecular-rotational components of the transient nonlinear refraction (NLR) of ambient air in the Mid-infrared spectral range below the ionization threshold.

Abstract

An investigation of Ir(III) complexes has been performed using double-pump probe (DPP) experiments to decouple the triplet quantum yield and triplet cross-section of these complexes. Both femtosecond and picosecond DPP measurements are presented.

Subjects
Condensed Matter::Soft Condensed Matter, Nonlinear system, symbols.namesake, Chemistry, symbols, Analytical chemistry, Nonlinear optics, Molecule, Polarization (waves), Refraction, Refractive index, Raman scattering, Nonlinear refraction
Abstract

The nonlinear refractive transients of organic solvents are measured. The response functions derived from liquids are used to predict pulsewidth dependent n2,eff . Comparisons are made between the second hyperpolarizabilities measured in liquid and gas phases.
