SHOW PREVIEW LASYS Material magic


Lasys will take place in Stuttgart, Germany from 24 to 26 June. Here we take a look at some of the technology that will be on display at the laser material processing trade fair


4Jet Technologies will showcase its product range for laser-based surface processing systems. The company supplies laser machines for micromachining products such as solar cells, displays and OLEDs, as well as large area laser cleaning systems that are used in the automotive industry. Some of the featured applications include the laser processing of thin display glass, and laser thin-film patterning of OLED components. www.4jet.de


CeramOptec Industries will be available to discuss both fused and continuous fibre optic tapers for use from the deep UV to NIR wavelengths. Produced with Optran all silica fibres, these tapers can be made with a taper length typically in the range of 5mm to 100mm. The development team has solved the problem of mechanically protecting the taper region by placing it in a fibre connector. The fibre core diameters that CeramOptec offers are within 50µm to 1,000µm. www.ceramoptec.com


Fianium will show its Hylase system, along with processed samples at this year’s show. The new micro-joule class


picosecond materials processing laser system provides up to 125µJ pulse energy with a small footprint. It is well suited to high speed, non- thermal, precision micromachining of semiconductors, dielectrics, metals, and polymer materials. Dr Tim Gerke, senior applications engineer at Fianium, will present a paper High Energy Picosecond Laser Material Processing at the Lasers in Action Forum on 26 June. www.fianium.com


EXECUTIVE PANEL DISCUSSION


Lasys will play host to an executive panel discussion featuring executives from the industrial laser marketplace. The discussion will take place


www.electrooptics.com |


from 13:00 to 14:00 on 25 June as part of the Lasers in Action Forum, which is jointly organised by Messe Stuttgart and Electro Optics’ sister title,


@electrooptics


Laser Systems Europe magazine. The panellists will be Georg Hofner, CEO at Scanlab; Wolfgang Schulz, head of department (modelling and simulation)


at Fraunhofer Institute of Laser Technology; Toni Koszykowski, CEO of Laser SOS Group; and Mario Ledig, vice president of Jenoptik Laser. The panel


will be moderated by Laser Systems Europe’s publishing director, Warren Clark. www.messe-stuttgart.de/ en/lasys/


JUNE 2014 l ELECTRO OPTICS 25


Coherent will be present to discuss its selection of products for materials processing, including CO2


, high power


diode, solid-state, ultrafast and fibre lasers, for everything from precision micro-processing to high speed metal cladding.


The company will show its HighLight 10,000D. The direct-diode laser system


Fraunhofer IPM will present its solutions based on techniques such as parallel computing either on GPU boards or on cellular neural networks, which guarantees increased processing speed and lower response times. The IPM systems achieve real time surveillance of the keyhole geometry with frame rates of up to 10kHz in laser welding processes or 3D measurements of sub-micron deformations with frame rates of up to 500Hz. Such techniques provide the possibility of measuring the impact of laser-based processes on the workpiece in real time. In laser drilling processes, for instance, the bottom break through can be observed with frame rates of up to 25kHz. In laser welding, closed-loop systems allow replacing full penetration by partial penetration weld seams, increasing productivity by about 30 per cent. www.ipm.fraunhofer.de


Jenoptik’s Lasers and Material Processing division will be displaying its Votan BIM and W laser systems, as well as the


multi-kilowatt fibre laser JenLas Fiber CW 3000 and the femtosecond laser JenLas Femto 10.


outputs 10kW (at 975nm), and this high power translates into increased throughput for applications in metal cladding and heat treating. The HighLight 10,000D is also a flexible solution, which can be configured to deliver a wide variety of interchangeable beam shapes (with widths from 1mm to 12mm, and lengths from 6mm to 36mm). www.coherent.com


The robot-based Jenoptik-Votan BIM (Beam in Motion) laser machine for 3D metal cutting provides industrial producers with a flexible, fast and cost-effective solution for the processing of metals and plastic materials. In order to broaden the spectrum of applications of laser penetration welding, the company has developed a welding process involving a laser line that can be activated and deactivated in sections. www.jenoptik.com


Vonjan Technology will show laser system components such as fibre lasers (1,064nm), DPSS lasers (532nm, 355nm),


two-axis scan heads, three-axis scan heads, and f-theta lenses for 1,064nm, 532nm and 355nm. It will also launch its two new scan heads, the RL-12 and the SS-9, as well as its new cost optimised MFP-Q fibre laser series. The company will demonstrate a set of matching components for an easy integration into a 1,064nm fibre laser system consisting of a 20W fibre laser, a scan head with a 12mm aperture, and an F-Theta lens (f=160). www.vonjan-tech.de
