It is also possible to manufacture a DOE with a fixed intensity ratio between the spot and the ring as a custom item using a single element!
The "FLEXI Beam Shaper" is a diffractive optical element (DOE) that allows for variable adjustment of the intensity ratio between the spot (center) and the ring (surrounding area). The propagating beam is shaped by rotating two diffractive optical elements (DOE) arranged along the optical axis, transforming it from a spot (up to 100%) to a concentric ring (approximately 80%). Of course, the intensity ratio between the spot and the ring can be continuously and variably controlled. 【Features】 ■ The challenges of high-power laser welding processes are not just about laser power ■ Adjustable intensity ratio for a special intensity profile (spot + concentric ring) ■ Suitable for applications such as sputtering, humping, undercutting, and welding porosity *For more details, please download the PDF or feel free to contact us.
