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.
Element Six will showcase its Optical+ Low Absorption diamond, which can be used as a low loss intra-cavity heat spreader for high power disk lasers, as well as a gain medium for Raman lasers. Raman crystals are offered in sizes up to 6x6x2mm, with larger sizes available on request.
Also featured will be the company’s Diamond PureOptics range. Drawing inspiration from the anti-reflective structure of a moth’s eye, this all-diamond solution offers improved reliability and even higher power density levels for high power CO2 laser systems. Diamond PureOptics exhibits a significantly higher laser induced damage threshold (by a factor of 10) than anti-reflective coated windows, with equivalent reflectance (less than 0.5 per cent) and transmission (above 99 per cent). The diamond-structured surface is designed to reduce reflection losses and replace typical anti-reflective thin film coatings found on diamond optical windows.
The TM200 bulk heat spreader also being shown offers high thermal conductivity – more than 2,000W/mK at room temperature – providing greater reliability and reduced system size in optoelectronic high power and high power density devices.

Nanoscribe will be displaying its Photonic Professional GT, a 3D printer for 2D, 2.5D and 3D structuring on the nanoscale to the mesoscale. The resolution is reflected in sub-micrometre details down to a structure size of 200nm, as well as the achievable surface roughness in optical quality.
Polymeric materials are exposed and cured by a laser lithographic process based on two-photon polymerisation. High-precision voluminous structures with an edge length of a few millimetres or micro-structured surfaces with elongation down to the square centimetre range can be printed on various substrates with a nearly unlimited freedom of design.
The user-friendly workflow is based on conventional 3D printer standards. Specially developed process solutions as well as photoresists give maximum mechanical stability, shape control and surface smoothness. The printer sets standards for science and industry, for example in photonics, micro-optics, microfluidics, life sciences, medical and sensor technology.

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.
Scanlab will be exhibiting the PowerScan II, a new 3D scan solution for industrial cutting and welding applications using CO2 lasers. This 50mm system offers small spot sizes and large working fields. Its low-mass mirrors also make it ideal for the highly dynamic cutting of paper and cardboard packaging, as well as textile marking or the welding of metal components via multi-kilowatt lasers.
The solution’s usage flexibility is emphasised by a motor-controlled Flex function that enables continuously variable image field sizes from 250 x 250mm² to 1,500 x 1,500mm². Simultaneously, various spot diameters and working distances are achievable. The iDrive technology permits multiple application-specific tunings, for example for complex cutting shapes with many angles, or for line-by-line bitmap marking at high line speeds.
The PowerScan II’s compact design enables the deployment of several scanners arranged in parallel within a confined space, to facilitate simultaneous processing in overlapping image fields.
