Description

Sorface plasmon polaritons (SPP) and their localized versions (LSPP) have numerous special properties, opening the way to a high number of applications. One group of these applications is connected with the generation of plasmons in extremely high EM fields, being the topics of the present talk. High intensity femtosecond laser pulses have been used for the plasmonic excitation. The created extremely high electromagnetic field intensity in the plasmonic hot spots has been explored. to study electronic and nuclear processes in some resonant nanoparticle doped transparent materials or on metallic (gold) surfaces . Some experimental results and their theoretical explanations are briefly presented. Time-of-flight multiplasmon electron emission analysis, scanning tunneling microscopy, Raman sectroscopy and laser induced breakdown spectroscopy methods have been used to get the experimental data The results of some of our experimental results and theoretical findings are briefly presented.
