"Fibre-delivered 1µm wavelength laser sources (i.e Yb-fibre and Yb:YAG disc) have the potential to revolutionise commercial laser cutting, which is currently dominated by CO2 lasers. Currently, 95% of lasers used in cutting applications are CO2 lasers, of which ~40% are used in Europe. The potential benefits of replacing CO2 lasers with new, 1µm wavelength fibre or disc lasers are significant, in ...
