XIII Escola de Verão Jorge André Swieca de Ótica Quântica e Ótica Não Linear - 2012
A total internal reflection-based differencial refractometer, capable of measuring the real and imaginary parts of the complex refractive index in real time, is presented. The device takes advantage of the phase difference acquired by s- and p-polarized ligh.

We demonstrate the fabrication of super-hydrophobic polymeric surfaces through laser microstructuring. Using 70-ps pulses from a Q-switched and mode-locked Nd:YAG laser at 532 nm, we fabricated a square-shaped pillar pattern, which leads to a substantial increase in the surface contact angle.
