Axicon array laser beam shaper can handle high peak and pulsed power
These beam shapers have an array of axicons typically arranged in a hexagonal pattern, which in combination with a collimated multi-mode input beam form to create a ring-shaped spot. By precisely controlling the angle of the axicon and the tip radius, PowerPhotonic can adjust the ring diameter, the level of extinction in the centre of the ring, and the width of the ring.
This type of optic is only made possible by using PowerPhotonic’s unique laser machining fabrication process, which allows it to create arbitrary shapes in UV-fused silica. The new family consists of a small number of readily available standard products, with low cost options to customise the key parameters of the design should the need arise. Typical applications for the axicon arrays include materials processing such as additive manufacturing and welding, laser diagnostics and research applications requiring a ring-shaped laser output.
