Dynamic control of directional asymmetry observed in ultrafast laser direct writing
- Abstract:
-
A liquid crystal spatial light modulator (SLM) is used to control the focal symmetry and the associated directional quill effect encountered when using a femtosecond laser for direct laser writing of fused silica. Applying a blazed grating to the SLM effectively introduces pulse front tilt to the fabrication beam and a spatiotemporal asymmetry at the focus. As a result different fabricated features are generated when moving the substrate in opposite directions relative to the tilt. It is addi...
