PROVIDENCE, R.I., March 29, 2012 — A line of oxygen-free high-thermal-conductivity (OFHC) copper mirrors is being offered by Laser Research Optics, with or without water cooling, for high-power multikilowatt CO2 laser systems. They are available in polished, uncoated versions, or with plasma gold coatings. Providing >99.6% reflectivity at 10.6 μm with λ/4 wave surface accuracy, they are designed for laser beam delivery and beam shaping. Available in 1- to 3-in. outside diameter sizes, the mirrors feature a clear aperture of 90% of the diameter and are effective for beam bending in all beam paths and beam guidance systems, from simple measurement setup to high-performance lasers.
