Campus, Bldg. 1, 2nd floor, Conference RoomSurface 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 the present work localized plasmons 
(LSPP) have been resonantly excited by ultrashort (n.10fs), high intensity 
(up to n.1018 W/cm2) pulses of Ti:Sa lasers on gold nanoparticles, implanted 
into a transparent polymer. The laser shots created craters in the studied 
samples. The volume of these craters is presented as the function of the 
exciting laser intensity for the samples with and without resonant gold 
nanoparticles as well as the creation of deuterium in the nanoparticle seeded 
sample with Raman and LIBS spectroscopy. Preliminary data indicate 
significant energy production and also nuclear transmutation (hydrogen to 
deuterium), clearly proving the decisive role of the unique properties of the 
LSPP-s. BN seeded samples have also been studied, where the p11B reaction has 
been observed by Thompson parabola measurements and by detecting α particles. 
Data obtained by other techniques ( mass spectrometry ) are also 
presented. Minden érdeklődőt szívesen látunk! - Everyone is welcome to
