WebConcentric circles and spot beams. A FLEXI beam shaper is a diffractive molding solution consisting of two identical diffractive optical elements (DOEs) located on the same optical axis. By rotating this DOE with each other, the beam propagating in it can be formed from a spot (100% output) to a ring with almost no energy in the spot (about 80% ... WebA beam shaper is an element that a single-mode beam is converted into a flattop beam, a ring-mode beam or a ring + center mode beam. This is effective in cutting, welding, …

Two-mirror beam-shaping technique for high-power diode bars [J]. Optics Letters, 1996, 21(6): 375–377. DOI: 10.1364/OL.21.000375. Article Google Scholar WebWe report a beam-shaping technique that reconfigures the beams to improve the beam quality and enhance the power density for a ten-array high-power laser-diode stack by using two optical rectangular cubes and two stripe-mirror plates. The reshaped beam has threefold improvement in beam quality, and its power density is effectively enhanced.
