Red laser creates nonlinear effects with tiny triangles of gold
A red laser creates nonlinear effects with tiny triangles of gold. The blue beam shows the frequency-doubled light and the green beam controls the hot-electron migration.
[Research performed in part at Georgia Tech's Institute for Electronics and Nanotechnology, a member of the National Nanotechnology Coordinated Infrastructure, which is supported by NSF grants ECCS 1542174 and ECCS 1609567.]
