Two-photon anisotropy: Analytical description and molecular modeling for symmetrical and asymmetrical organic dyes
(Elsevier Science BvAmsterdamHolanda, 2006)
Investigation of the two-photon absorption cross-section in perylene tetracarboxylic derivatives: Nonlinear spectra and molecular structure
(Amer Chemical Soc, 2006-05-25)
We investigated the 2PA absorption spectrum of a family of perylene tetracarboxylic derivatives ( PTCDs): bis( benzimidazo) perylene ( AzoPTCD), bis( benzimidazo) thioperylene ( Monothio BZP), n-pentylimidobenzimidazoperylene ...
Degenerate Two-Photon Absorption in All-Trans Retinal: Nonlinear Spectrum and Theoretical Calculations
(AMER CHEMICAL SOC, 2010)
In this work we investigate the degenerate two-photon absorption spectrum of all-trans retinal ill ethanol employing the Z-scan technique with femtosecond pulses, The two-photon absorption (2PA) spectrum presents a monotonous ...
Two-photon absorption spectrum in diazoaromatic compounds
(Elsevier ScienceAmsterdam, 2008-10)
This Letter studies the degenerate two-photon absorption (2PA) spectra of three diazoaromatic compounds using Z-scan with fs-pulses. The 2PA spectra exhibit resonant enhancement of the nonlinearity as the excitation ...
Perylene derivatives with large two-photon-absorption cross-sections for application in optical limiting and upconversion lasing
(Wiley-Blackwell, 2005-08-04)
Perylene tetracarboxylic derivatives (PTCDs) display exceptionally high two-photon absorption (2PA) cross-sections (6, see Figure). In addition, the 2PA saturation behavior and strong two-photon-pumped fluorescence suggest ...
