High-Efficiency Fabrication of Geometric Phase Elements by Femtosecond-Laser Direct Writing
The nanoresolution of geometric phase elements for visible wavelengths calls for a flexible technology with high throughout and free from vacuum. In this article, we propose a high-efficiency and simple manufacturing method for the fabrication of geometric phase elements with femtosecond–laser direc...
