Imaging with Diffractive Axicons Rapidly Milled on Sapphire by Femtosecond Laser Ablation

Daniel Smith, Soon Hock Ng, Molong Han, Tomas Katkus et al. • Engineering Proceedings (2023)

We show that single-pulse burst fabrication will produce a flatter and smoother profile of axicons milled on sapphire compared to pulse overlapped fabrication which results in a damaged and much rougher surface. The fabrication of large-are...
