UrduAdvances in information technology demand complex micro-optical elements with nanoscale precision. Femtosecond laser direct writing (FsLDW) rises to the challenge, using ultrashort pulses to create three-dimensional micro-nano structures. This versatile technique boasts diverse material compatibility and can fabricate imaging and non-imaging micro-optical elements, opening doors for next-generation stereoscopic systems.
