  • Copper Mirrors for CO2 Lasers
Dec 2011
Research Electro-Optics Inc. (REO)Request Info
BOULDER, Colo., Dec. 8, 2011 — REO Inc. now offers a variety of copper high reflectors suitable for beam-delivery and beam-shaping tasks involving high-power CO2 lasers. The mirrors offer reflectivity of >99.7% at 10.6 µm, surface quality of 40-20 scratch-dig and low scatter surface roughness of <50Å. They are produced from oxygen-free, high thermal conductivity copper to deliver good optical performance and a maximum laser damage threshold.

The laser mirrors can be produced with plano, spherical or cylindrical surfaces over the 6- to 150-mm size range. Through-holes, mounting flanges and other mechanical features easily can be accommodated.

High-power CO2 laser beams can be stressful to dielectric coatings, and the design and production of the coatings often involve trade-offs in performance, lifetime and cost. For this reason, the company employs either traditional electron beam or advanced plasma source coating technologies to deliver the precise combination of durability, damage resistance and cost characteristics required for a specific application.

The optics are handled in a controlled environment throughout the manufacturing process, preventing any deterioration of the pristine optical surfaces prior to coating, and maximizing thin-film adhesion and the laser damage threshold.
