| Outline of Final Research Achievements |
In this study, we investigated interaction between femtosecond laser pulses and materials including photoresists and metallic nanostructures. When highly-repetitive focused femtosecond laser pulses with low-NA lenses, specific channel propagation could be observed. We revealed that the origin of such propagation was heat accumulation effect. In addition, femtosecond laser pulses induced plasmonic modes on metallic nanostructures, resulting strong electromagnetic field on metal surfaces. Optical experiments and theoretical analysis show that such strong electromagnetic fields affect multi-photon reduction in AgNO3 solution.
