Water-Cooled Mirrors for High-Power Lasers
Operate reliably at high laser powers with these water-cooled metal mirrors which can be made up to 300 mm in diameter and include various light-weighting features.
Diamond turned aluminum mirrors for 1 μm lasers offer weight savings for faster cutting head motion, while copper mirrors for 10.6 µm lasers have the highest cooling efficiency. Aluminum mirrors can be polished to sub-nanometer surface roughness.
