Laser patterning of DRUM-moulds for large area nano-imprinted polymer foils
- Defining of optimized hierarchical patterns suitable for efficient laser direct writing and the addressed application; defining the assessment protocols;
- Optimization of the processing parameters and the processing methodology for the hierarchical pattern writing in a two-step strategy;
- Synchronization of the scanner with the rotation axis for high-resolution writing;
- Verification of the laser direct writing of hierarchical surface patterns for NIL cylinder fabrication and manufacturing of suitable structured plastic foils with laser-written cylinders.
