Random lasers operate without a traditional resonator cavity compared with traditional
lasers, instead relying on multiple scattering events within a disordered medium to amplify …

The properties of random lasing are investigated for bubble-structure (BS) dye-doped
polymer random media in which non-scattering and no-gain regions are distributed …

Heterojunctions made by depositing Titanium dioxide (TiO 2) on porous silicon using the sol-
gel method were electrically characterized. It was found that charge transfer mechanisms …

This paper prepares and investigates superhydrophobic silica aerogels doped with Crystal
Violet dye. The primary contribution is to obtain a product with the best specifications in the …

In this work, we developed optically active polymeric composite which are employed as gain
medium in random laser systems. Single-walled carbon nanotubes were added to the …

Neste trabalho, são descritos os estudos do fenômeno de laser aleatório (LA) em amostras
poliméricas flexíveis contendo centros espalhadores obtidos naturalmente. O LA foi …

Considerando o aumento das emissões globais de CO2 na atmosfera, diferentes
estratégias vêm sendo desenvolvidas para diminuir e mitigar a geração deste gás estufa …
