Due to its multispectral transparency, CaF2 – alongside Zinc Sulphide (ZnS) – crystals have been brought into an experiment for ultrafast laser microsurgery applications. Here, researchers constructed a diamond-turning device to produce both these compounds into lenses with a surface roughness of 6 and 5nm, respectively, to: “Withstand the high power from ultra-short laser pulses and provide a tightly-focused beam with 1.23μm 1/ e2 spot radius for laser ablation”.
