Outline of Final Research Achievements

I have studied the fundamental research on the control of the nanostructure formation on solid surfaces induced with femtosecond laser pulses, resulting in the formation of homogeneous nanograting with the size of 25 nm. The simple two-step ablation process has been developed to control the surface plasmon polaritons and the intense near fields on the target surfaces with the femtosecond laser pulses.
