Femtosecond laser pulse propagation in a metallic nano-slit array Download: 540次
Abstract
The property of femtosecond laser pulse propagation in a metallic nano-slit lens, which is composed of nano-slits with variant widths, is investigated by using the finite-difference time-domain method. By appropriately setting the width profile of the arrayed nano-slits, we find that the femtosecond laser pulse can be focused on a nano-scale spot, while the pulse shape is well maintained beyond the spot location.
