Peter Hagelstein hypothesized that SPPs could form on the surface and that they may be complicit in the conversion of the 2 laser signals into the beat frequency. The SPPs could potentially provide the nonlinearity required for a beat to form. In past experiments, the amount of gold needed for th

Hi Jones, Here's FYI of something similar, Jones, et al. When I was young and dumber I knew of a Dr. Cameron Jones who no longer works at Swinburne Uni. where he diluted colloidal gold to the proper density to get the correct spacing that entertained a plasmon resonance when painted on a sur

The possibility of an energy anomaly based on gold plasmons from nanoparticles being irradiated by lasers –using beat frequency or not - leads to an idea for a simple low cost experiment. Gold nanoparticle colloids are available at remarkably low prices due to growing use as cure-all dietary
