Surface plasmon polaritons are the light of the nanoworld, with a broad spectrum of special properties. These properties open the field for a high number of applications, both in the fields of low and high intensities. In polymer samples, localized surface plasmon polaritons (LSPPs) have been resonantly excited by ultrashort (n. 10 fs), high intensity (up to n. 1017 W/cm2) pulses of a Ti:Sa laser on gold nanoparticles, implanted into the transparent polymer, and this the laser shots created craters. The volume of these craters is presented as the function of the exciting laser intensity for the samples with and without resonant gold nanoparticles, and the creation of deuterium in the nanoparticle-seeded sample was studied with Raman and laser-induced breakdown spectroscopy (LIBS). The preliminary data indicate significant energy production and nuclear transmutation (hydrogen to deuterium), clearly proving the decisive role of the unique properties of the LSPPs. Preliminary data of some nuclear (CR-39) methods are also described. Thompson parabola energy analysis of particles after laser shots indicates proton–boron fusion reaction.
