Dynamic control of directional asymmetry observed in ultrafast laser direct writing
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 fa...
