Excited-state absorption spectroscopy in oxidized Cytochrome c
(ELSEVIER SCIENCE BV, 2010)
This work reports on the excited-state absorption spectrum of oxidized Cytochrome c (Fe(3+)) dissolved in water, measured with the Z-scan technique with femtosecond laser pulses. The excited-state absorption cross-sections ...
Equation for modeling two-photon absorption in nonlinear waveguides
(Optical Society of America, 2020-06)
We derive a novel propagation equation for optical waveguides that properly accounts for two-photon absorption (TPA). We start from a simple quantum theory of nonlinear fibers allowing for TPA to be included in a straightforward ...
Facile Synthesis of Tellurium Nanowires and Study of Their Third-Order Nonlinear Optical Properties
(Sociedade Brasileira de Química, 2017-01-01)
We report on the synthesis of single-crystalline tellurium nanowires with different aspect-ratios prepared via facile surfactant-assisted synthesis under mild conditions. Short and long Te nanowires were synthesized by the ...
Ablation and optical third-order nonlinearities in Ag nanoparticles

Optical limiting behavior of tungstate fluorophosphate glasses
(2003-12-01)
Nonlinear absorption measurements were performed on fluorophosphate glasses with high concentration of tungsten oxide. Large two-photon absorption coefficients, α2, were determined at 660 nm using nanosecond laser pulses. ...

Study of absorption spectrum and dynamics evaluation of the indocyanine-green first singlet excited state
(WILEY-BLACKWELL, 2011)
Excited state absorption and excited state dynamics of indocyanine-green (ICG) dissolved in dymethyl sulfoxide were measured using white-light continuum Z-scan (WLCZScan) and white-light continuum pump-probe (WLCPP) ...
Broadband three-photon absorption spectra of platinum acetylide complexes
(Optical Society of America - OSAWashington, DC, 2011-08)
We investigate the three-photon absorption spectra of four platinum acetylides complexes employing femtosecond pulses. We observed strong three-photon absorption cross-section in the near-infrared region (from 850 nm to ...
