1. MATERIAIS VÍTREOS E LUZ: PARTE 1
2015 is the Year of Light, according to UNESCO. Chemistry has a close relationship with light and one of the materials that allows such synergy is glass. Depending on the chemical composition of the glass, it is possible to achieve technological applications for the whole range of wavelengths extending from the region of the microwave to gamma rays. This div

2. Nonlinear Optical Properties and Femtosecond Laser Micromachining of Special Glasses
Materials specially designed for photonics have been at the vanguard of chemistry, physics and materials science, driven by the development of new technologies. One particular class of materials investigated in this context are glasses, that in principle should exhibit high third order optical nonlinearities and fast response time, whose optical properties c

4. Nonlinear optical properties of organic and organometallic compounds / Propriedades ópticas não lineares de compostos orgânicos e organometálicos
In the last few years, the design and characterization of novel materials exhibiting high optical nonlinearities is the subject of a fast-growing interest because of their potential application in various fields, from biology to photonics. Two-photon absorption processes, for example, have been used for optical limiting, three-dimensional microfabrication, o

5. Caracterização das propriedades ópticas não lineares de vidros teluretos, líquidos orgânicos e colóides de nanopartículas de ouro. / Characterization of the nonlinear optical properties, nonlinear refraction, thermo-optical coefficient, photonics-nonlinear materials.
Nesta tese, investigamos as propriedades ópticas não lineares de quatro sistemas físicos distintos: vidros teluretos, óleo de mamona, líquidos iônicos e colóides de nanopartículas de ouro. Utilizando as técnicas de varredura Z (Z-scan) e varredura de intensidade (I-scan) foi possível determinar os valores das contribuições de origem eletrônica (
