TL;DR: In this paper, the authors utilize the recently demonstrated orders of magnitude enhancement of extremely nondegenerate two-photon absorption in direct-gap semiconductor photodiodes to perform scanned imaging of 3D structures using IR femtosecond illumination pulses (1.6 um and 4.93 um).

TL;DR: In this article, the nonlinear optical properties of carbon black particles in liquids and layers of glass are characterized and the limiting is dependent on the energy density (fluence) and the material changes from a linear absorber to a nonlinear scatterer for fluence levels 0.2 J/cm2 and 0.38======J/cm 2 for 0.532 jim, 14 ns and 1.064 pm, 20 ns laser pulses respectively.

TL;DR: In this paper, an increase in the dynamic range of an optical limiting device is achieved by using two different nonlinear elements cascaded within a single limiting device, and a comparison between the results of optical limiting experiments for a single nonlinear element limiter and a two-element limiter shows a significant increase in damage threshold of the latter with only a small increase of the limiting threshold.

TL;DR: In this article, the synthesis, structural characterization and photophysical study of a series of compounds (model, oligomer, and polymer) with symmetric molecular structure of the Dπ-D motif and branched D-π -D dendrimeric structures based on substituted fluorene derivatives were described.

TL;DR: A new phosphonium-containing cationic polyelectrolyte (PE1) has been rationally designed and developed via a facile click-chemistry type postfunctionalization, which can form complexes with highly polarizable anionic cyanines to significantly reduce the strong and ran-dom cyanine-cyanine interactions in the solid-state.
