| Outline of Final Research Achievements |
In this study, we studied direct formation of two-dimensional metal micro- and nanostructures by laser-induced forward transfer (LIFT) using single pulse of a femtosecond laser. Single pulse of a femtosecond laser with a flat-top intensity distribution was exposed to two-dimensional metal structures prepared by laser lithography or nanoimprint lithography on a transparent substrate. According to the research, four following results were obtained; 1. A LAL contributed to reduction of the energy threshold for ablation reaction by single pulse of a femtosecond laser. 2. Two-dimensional metal structures were formed on an acceptor substrate by LIFT. 3. Ablated metals were fused and coalesced then deposited on an acceptor substrate by LIFT. 4. Metal films formed on a UV-imprinted patterns were selectively removed by single pulse of a femtosecond laser.
