Abstract
Second harmonic generation of ferroelectrical nano- and microparticles embedded in a nanostructured silica aerogel and xerogel matrix was observed. A homogenous distribution of the ferroelectrical powder was achieved during microgravity on parabolic flight. The paper describes the synthesis procedures of this new class of random non-linear optical materials. The experimental results on frequency doubling are explained with a simple model of absorption and transmission.
