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

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-area (sub-1 cm cross-section) micro-optical components in a sho...
