PowerPhotonic beam shapers can generate ring-shaped spots

Axicon array beam shapers for use with high-power single- and multimode lasers reach efficiencies of >98%. They can generate ring-shaped spots, either as a single axicon, or as an array for multimode laser homogenization. The optics are capable of handling >100 kW of continuous-wave laser power.
