PRODUCT UPDATE OPTICS High power beam transformation systems


Limo Lissotschenko Mikrooptik has released a high power Beam Transformation System (BTS) made from ultra-pure fused silica. The optics are designed to deliver the best possible performance and beam quality in laser systems with output powers of more than 10kW. The new High Power BTS, made of fused


silica, remains thermally stable – even in high- performance industrial applications – and thus ensures reliable functionality across the entire laser system. Extremely high transmission rates


Axicon array beam shapers


PowerPhotonic has launched a family of axicon array beam shapers for use with multimode lasers. Capable of handling very high peak and pulsed power, the arrays can be used to generate ring-shaped spots, a typical requirement for material processing applications. These beam shapers have an array of axicons – conical-surface lenses – typically arranged in a hexagonal pattern that, in combination with a


of more than 98 per cent are achieved thanks to the ultra- pure fused silica. The new BTS


can be used both to couple laser light into a circular fibre and produce a free laser beam. With a pitch of 200 or 400µm, the system is capable of coupling up to 50 emitters with an output of approximately 250 to 500W per bar and a 50 per cent fill factor. www.limo.de


CONTROL AND GUIDANCE BasiCube 10


collimated multimode input beam, creates a ring- shaped spot. By 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. The beam shapers exhibit very high transmission efficiencies, up to 98 per cent, thanks to an ultra-smooth low-scatter optical surface. www.powerphotonic.com


New to Scanlab’s compact class of scan heads is the BasiCube 10, a system optimised for use with 532nm green laser light that excels in laser marking applications, as well as in laser-based internal glass engraving. The same applies to the processing of precious metals, silicon wafers and other materials that respond poorly to typical infrared wavelengths. Lasers at 532nm wavelength produce fine contours by focusing the beam to very small spot sizes while simultaneously maintaining excellent beam quality and low heat development. In this way, 3D shapes can be engraved inside a glass body or copper wires welded directly onto silicon substrates of integrated circuits. A wide range of application areas for the scan system includes medical products, decorative items or jewellery, and applications in the semiconductor industry. For equal writing performance, this system uses less electrical power compared to other systems, thereby also improving the system’s positional stability under load. www.scanlab.de
