The search for optical materials, particularly organic compounds, is still an attractive and essential field for developing several photonic devices and applications. For example, some applications are based on light scattering with twice the energy

Nanomaterials have been investigated as saturable absorbers for ultrafast lasers because of their large photoinduced transparency related to ground-state bleaching. However, the quantum dot size effect on the photoinduced transparency in the strong c

Publikováno v: Langmuir : the ACS journal of surfaces and colloids. 38(49)

An experimental-theoretical approach is proposed to investigate the size-dependent photobleaching of colloidal semiconductor quantum dots (QDs) excited by a nanosecond pulsed laser. In the experimental background, the ground-state absorption and phot

Spectral Dependence of the First Order Hyperpolarizability β in Butadiene Derivatives by HRS Technique Applying Ultrashort Pulses Laser

Autor: Carlos H. D. Dos Santos, Leandro H. Z. Cocca, André Pelosi, Cleber R. Mendonça, Leonardo De Boni

Publikováno v: Latin America Optics and Photonics (LAOP) Conference 2022.

In literature there are few papers that report to spectral dependence of β(λ), therefore, we apply the HRS technique to obtain this dispersion. The experimental results show an excellent agreement with theoretical values.

Incoherent Molecular Second-Order Scattering Dispersion Measured from One- and Two-Photon Absorption Photophysical Parameters

Autor: Lucas F. Sciuti, Luis M. G. Abegão, Carlos H. D. Dos Santos, Leandro H. Z. Cocca, Rafaela G. M. Da Costa, Jones Limberger, Lino Misoguti, Cleber R. Mendonça, Leonardo De Boni

Publikováno v: Latin America Optics and Photonics (LAOP) Conference 2022.

We determine the incoherent molecular second-order scattering dispersion β(λ) applying the semi-classical time-dependent perturbation theory on experimentally observable electronic transition whose properties were measured with one- and two-photon
