The ability to water-cool aluminum mirrors allows for lighter-weight processing heads, enabling faster cutting and welding. Aluminum offers a significant reduction in weight and corrosion compared to equivalent copper parts. For 1μm applications, aluminum mirrors can be post-polished to achieve sub-nanometer roughness in fold mirror configurations and deposited with a highly-reflective, dielectric coating for >20 kW power usage.
