Demonstrating Frequency Doubling in Titanium Dioxide

Caption

Georgia Tech researchers Kyu-Tae Lee and Mohammad Taghinejad demonstrate frequency doubling on a slab of titanium dioxide using a red laser to create nonlinear effects with tiny triangles of gold. The blue beam shows the frequency-doubled light and the green beam controls the hot-electron migration.
