The picosecond laser Atlantic for micromachining is available as a compact, entirely air-cooled model. TOPAG offers this laser from the manufacturer Ekspla with 10 ps pulse duration in three variations. Atlantic IR5 delivers an average power of 5 W at 1064 nm. The model Atlantic GR2 offers the choice between 2 W at 532 nm and the fundamental wavelength. Meanwhile, Atlantic UV1 only delivers 1 W at 355 nm. For all wavelengths, the laser stands out by its excellent pulse-to-pulse stability.

Die Idee, Ultrakurzpulslaser für die »athermische« Probenpräparation nutzbar zu machen, hatte Höche bereits 2010. Am IMWS führte er sie mit Dr. Michael Krause weiter. »Wir benutzen einen Pikosekundenlaser mit Pulslängen von einer Billionstel Sekunde, um die Erhitzung des Probenmaterials zu vermeiden«, erläutert Krause. Die Anlage microPREP™ entwickelten Krause und Höche zusammen mit der 3D-Micromac AG in Chemnitz – Höches ehemaligem Arbeitgeber. Im Prototyp erfolgt die Probenpräparation in zwei Schritten: Ein mechanisch zugeschnittenes Stück des Probenmaterials erhält mit dem Ultrakurzpulslaser eine definierte Form und kann gleichzeitig beschriftet werden – was Verwechslungen ausschließt und bei Kunden großen Anklang findet. Im zweiten Schritt wird an einer bestimmten Stelle der Probe eine Fläche auf unter 15 Mikrometer »abgedünnt«, dabei arbeitet der Laser parallel zur Oberfläche.

Höche had the idea of using ultra-short pulsed lasers for the »athermal« specimen preparation back in 2010. At Fraunhofer IMWS he continued his idea with Dr. Michael Krause. »We use a picosecond laser with pulse lengths of one billionth of a second, to avoid heating the specimen material«, explained Krause. Krause and Höche developed the microPREP™ system together with 3D-Micromac AG in Chemnitz – Höche’s former employer. In the prototype the specimen preparation takes place in two steps: A piece of the specimen material cut to size mechanically is given a defined shape with the ultra-short pulse laser and at the same time can be labelled – which excludes mix-ups and is very much approved of by our clients. In the second step, in a certain area of the specimen, an area is >>thinned<< to less than 15 micrometres, here the laser works parallel with the surface. Following the laser preparation with microPREP™, the specimen is only briefly polished in a wide ion beam system or a focussed ion beam before it can be examined in the TEM. The microPREP™ developers are proud to offer specimen preparation that is not only faster, but is also much less expensive.

Dawid Cichowski studied at the Karlsruhe Institute of Technology (KIT) from 2007-2013 with a focus on BioMEMS engineering and energy technology. He completed an internship at Siemens Pte. Ltd. in Singapore as a mechanical engineer in the Division of Mobility & Logistics in the Sector of Infrastructure & Cities. Here he worked on all phases of the redesign of a baggage handling system. In his undergraduate (Vordiplom) thesis work he examined turbulence fields on small scales (micrometers) by stereo PIV and numerical calculations using a fine-structure model at the Institute of Fluid Machinery (FSM) at KIT. He completed his Diplom thesis work at TRUMPF Maschinen AG in Switzerland under the supervision of Professor Andreas Guber from the Institute for Microstructure Technology at KIT, entitled "Can Ablation Rates of the Picosecond Laser be Predicted?”. This work focused on basic research into understanding of the process of material removal from different materials by a picosecond laser. Since mid-2013 he is pursuing a doctorate at the Department of Microsystems Engineering (IMTEK) in the Lab for Design of Microsystems under the direction of Professor Peter Woias.

NUM collaborates with Chinese machine builder to develop advanced 8-axis CNC multi-function machining center * performs precision high speed laser cutting and milling with single clamping operation Naperville, IL, July 2, 2018 — CNC specialist NUM has helped the Chinese machine building company Original Point Machine Tools (OPMT) to develop an advanced 8-axis CNC machining center capable of processing many different types of materials, including metal, ceramics, glass and cemented carbide. OPMT is a relatively small but fast-growing company based in Fo’shan – of Guangdong Province – in south China. It is rapidly acquiring a reputation for innovative complex engineering: after developing a highly successful 4-axis milling center for an automotive production line, it then created a compact 5-axis milling station for the dental industry. For its latest project, OPMT was asked by Guangdong University of Technology to develop a machining center that combined high speed laser cutting and milling capabilities. This key provincial university is located in Guangzhou, Guangdong Province, China, and provides a wide range of courses, with a major emphasis on engineering. OPMT chose to partner with NUM for its CNC expertise and with the Xi'an Zhongke Microcrystalline Manufacturing Company and the Chinese Academy of Sciences to help with some of the complex materials processing issues. The result is the ML125 8-axis multi-function machining center. The machine has a dual laser head that is capable of switching between a 20 watt picosecond laser for very high speed cutting and an ultrafast 10 watt femtosecond laser for improved process quality. The femtosecond laser is capable of drilling and cutting almost any type of material, and its very short 1030 nm wavelength means that it is suitable for micro/nano processing applications. Entirely controlled by NUM’s latest-generation Flexium+ 68 CNC platform, the ML125 machining center has eight servo axes, two independent NC channels and fast application-specific I/Os embedded in the NCK hardware. Movement of the fully articulated laser head is controlled by five NUMDrive X servo drives, with high speed interpolation between all five axes – and the CNC system provides a full RTCP function. By employing a special hollow shaft torque motor and a linear motor drive, the dual laser head has an exceptionally high positional accuracy of 8 micrometers (0.008 mm), with a repeatability of just 5 micrometers. The associated A/C axis ro
