Abstract
The study compares two laser beam intensity distributions, namely the Gaussian beam and the flat-top, for micromachining applications at a UV wavelength of 257 nm (4th). A novel laser system with integrated beam shaping capabilities, including a flat-top intensity profile is introduced. The differences when micromachining materials using the top-hat intensity profile are compared to the conventional Gaussian intensity distribution.
