Dynamic optics for ultrafast laser processing

摘要

We present a range of dynamic optical methods to control focal fields for material processing using ultrafast lasers. Adaptive aberration correction maintains focal quality when focusing deep into materials. Dynamic parallelisation methods permit independent control of hundreds of fabrication spots. New adaptive methods for control of pulse front tilt are also presented.OCIS codes: 010.1080 – Active or adaptive optics / 140.3390 – Laser materials processing
