10-kW Laser Optics
II-VI Inc. (see Coherent Corp), II-VI Infrared
II-VI Inc. has announced a new line of optics designed for 10-kW class fiber and direct diode lasers.
The optics are made from low-absorbing fused silica substrates. They undergo magneto rheological finishing to achieve <λ/10 of surface irregularity and <1 nm of roughness. With a high-performance, proprietary ion beam sputtering coating, they achieve <10 ppm of total absorption loss. The 10-kW optics are available in many complex shapes used in today’s high power beam shaping applications such as aspheres, axicons and high aspect ratio lenses. Improved lens quality enables the lasers to maintain high reliability at high power levels and over long periods of time.
The next-generation fiber and direct diode lasers can be used in metal cutting and welding, as well as additive manufacturing.
