REO offers copper mirrors for high power CO2 lasers

REO, Boulder, Colo., now offers a range of copper high reflectors useful for beam delivery and beam shaping tasks involving high power CO₂ lasers.

In particular, these mirrors offer a combination of high reflectivity (>99.7% at 10.6 micron), excellent surface quality (40-20) and low scatter (surface roughness <50 angstrom), and are produced from OFHC (oxygen free, high thermal conductivity) copper to deliver superior optical performance and maximum laser damage threshold. These CO₂ laser mirrors can be produced with plano, spherical or cylindrical surfaces over the 6 mm to 150 mm size range. In addition, through holes, mounting flanges and other mechanical features can be easily accommodated.

High power CO₂ laser beams can be particularly stressful to dielectric coatings, and both the design and production of these coatings often involves trade-offs in performance, lifetime, and cost. For this reason, REO can employ either traditional electron beam (e-beam) or advanced plasma source (APS) coating technologies to deliver the precise combination of durability, damage resistance and cost characteristics required for a specific application. Furthermore, the optics are handled in a controlled environment throughout the manufacturing process, thus preventing any deterioration of the pristine optical surfaces prior to coating, and maximizing thin film adhesion and laser damage threshold.

REO produces high precision thin film coatings, optics and opto-mechanical assemblies for the ultraviolet, visible, and infrared regions.
