Abstract

Ultrafast laser processing considerably gains in efficiency when using liquid crystal based spatial light modulators (LCSLM) to tailor the laser beam shape for upgradedsurface or bulk structuring.The fidelity of the experimental beam shape when compared to the target intensity distribution is of great importance for precise and controlled machining. Due to the physical characteristics of LCSLM, their non-perfect optical response has to be taken into account when designing phase masks. In this contribution, we'll discuss phase mask optimization for LCSLM for several beam shapes and present some applications in surface, bulk processing as well as in ophthalmology.
