Applied Laser Engineering will exhibit its laser engraving systems, which are used to engrave high resolution 2D and 3D graphics into the surface of cylindrical and flat substrates for various printing, texturing, security and embossing applications.
The company’s range of laser engraving systems are made up of a high precision machine bed integrated with novel mechanisms and optical instrumentation together with specialised electronic, optical, computerised and laser equipment.
Machines range from 0.6-7 metres roller length capability, and up to 1 metre diameter. Laser type and wavelength is application or material specific. Materials processed include metals, ceramics, rubber, and natural and synthetic polymers. Engraving systems for ceramic anilox are a speciality. The company is developing its range of products to increase productivity, reduce production costs and to meet specific customer driven requirements.
Coherent-Rofin will show its new, 1kW average power pulsed fibre laser. The system offers the highest beam quality currently available at this power level, thus enabling high throughput, precision ablation for a variety of industrial and solar applications.
Specifically, the FP 010 delivers a maximum pulse energy of 100mJ, at pulse widths between 10ns and 100ns, and with repetition rates ranging from 10kHz to 30kHz. A beam parameter product of less than 24mm x mrad for a 400μm, round core output fibre enables this power to be concentrated into small focused spot sizes, potentially offering longer working operating distance or scanning over a larger field.
The FP 010 is constructed to be reliable and deliver high uptime in demanding, multi-shift industrial environments. The product uses field-proven components, while pump laser bars with a wide emitter separation minimises the impact of a single diode failure on overall system operation.
The FP 010 is an ideal source for ablation, surface cleaning, and precision material and coating removal in a range of applications. These include AlSi removal from tailored blank parts prior to welding, edge deletion for thin film (CdTe, CIGS) solar cells, cleaning of moulds, aerospace components and other precision parts, as well as other surface cleaning, activation and structuring uses.
Lasermet will demonstrate its Laser Castle, a modular laser safety cabin with a choice of auto or manual doors, and full dual-channel interlock control. It integrates active laser guarding in the form of Laser Jailer, and active filter window technology – Glaser Jailer – to provide virtually immediate switch-off of any multi-kilowatt laser beam that strikes the interior of the safety cabin. Turntables are catered for and Lasermet’s fume extraction systems can be integrated.
Lasermet also produces and certifies a range of industrial laser safety equipment and systems conforming to EN 60825. Services include FDA reports, training, laser testing, audits and risk assessments.
The company covers all laser safety aspects including LED warning signs, labels, optical table guards, laser blocking curtains, screens and roller blinds, modular enclosures, laser safety calculation software, filter windows, laser shutters (to PL‘e’) and dual-channel interlock controllers (to ISO13849-1 PL‘e’).
Ophir will display its BeamSquared device, an M2 laser beam propagation system that measures the quality of the beam to optimise performance. A compact, portable device, it provides automated measurements of the propagation characteristics of CW and pulsed lasers in less than one minute.
Users can run the system in automated mode from UV to NIR, and telecom wavelengths, and in manual mode for terahertz and CO2 laser beams. BeamSquared is designed for continuous use applications, from scientific research to rapid prototyping to fabrication and machining.
The system includes the BeamSquared M2 software; a high accuracy CCD, InGaAs, or pyroelectric array camera; and an optical train. The software measures beam propagation characteristics on both the X and Y axes, including waist diameters, full angle divergences, waist locations, Rayleigh lengths, M2 or K and BPP factors, astigmatism, and asymmetry. 2D or 3D beam profiles provide visual verification of beam profile behaviour through focus.
MKS Instruments’ Spectra-Physics business unit will exhibit IceFyre at the trade fair in Munich. Icefyre is a compact, high power industrial picosecond hybrid fibre laser with excellent cost performance.
IceFyre delivers exceptional performance with high power and short picosecond pulses, as well as having adjustable repetition rates, TimeShift ps programmability pulse flexibility, and pulse-on-demand triggering. Combining power supply and laser head in a single rugged and compact package, IceFyre enables easy system integration and has proven reliability and stability.
The new laser is ideal for picosecond cold micromachining in high throughput, precision manufacturing of sapphire, glass, ceramics, fine metals, plastics, and other materials and devices. IceFyre is designed for continuous manufacturing applications that were not previously technically and economically feasible.
