Ultra-high-aspect-ratio structures through silicon using infrared laser pulses focused with axicon-lens doublets
We describe how a direct combination of an axicon and a lens can represent a simple and efficient beam-shaping solution for laser material processing applications. We produce high-angle pseudo-Bessel micro-beams at 1550 nm, which would be difficult to produce by other methods. Combined with appropri...
