FiberLast also develops custom solutions for scientific applications that address specific challenging problems.

The company will present the fibre laser marking machine Flast-NanoMark. The most differentiated features of the company's fibre laser are independently adjustable pulse width and frequency, which provides more flexible operation to the user.

Along with these properties, the high peak power and beam quality of Flast-NanoMark provides unique marking opportunities to its user even at low powers. FiberLast’s fibre laser marking systems are effective on materials including metal, gold, leather, plastic, textile, ceramic, paper, polymer and others.

Laser On Demand

Laser On Demand (www.laser-on-demand.de) will be exhibiting at the show. The company offers reliable solutions for mobile laser processing, based on multi-kW lasers and industrial robots. Fully-rugged systems are suitable for adverse circumstances, such as construction site conditions or low temperatures. These devices are in use for a variety of applications: decontamination of radioactively contaminated components in nuclear power plants; cutting, welding or hardening of machine parts; and application of handheld systems for processing of large, less-portable components. Moreover, the use of these systems on a rental basis enables short-term projects such as tests under real-life conditions or a temporary increase in production capacity.

Lumera Laser

Lumera Laser (www.lumera-laser.com) will exhibit its line of picosecond lasers for micromachining applications in industry. Each picosecond pulse (with the proper parameters) will ablate a 0.1µm thin layer of material with minimum thermal side effects from the surface of any target material. Up to one million pulses per second offer a reasonable ablation rate of up to 60mm³/min and the reproduction of any 2.5D CAD structure directly into the materials.

The wide range of applications include dicing sapphire and cutting, drilling glass or hard metal and composite materials. More than 700 industrial systems operate worldwide in the production of LEDs, semiconductors, solar cells, touch panels, components for aerospace and car industry, for analytical devices, micro tools, printing and embossing rolls, or medical technology.

MRC Systems

MRC Systems (www.mrc-systems.de) will show its laser beam stabilisation products. The systems are used to stabilise the position and direction of laser beams against spatial fluctuations. Such fluctuations can be thermal or mechanical drift, vibrations, laser pointing, or shocks. Compensation can also be made for deviations due to a beam transfer over separate mechanical bases or optical tables.

The systems include a closed loop controller and one or two pairs of position detectors and mirror actuators. They are characterised by a high intrinsic stability without needing specific user interaction. The modular design enables a flexible definition of the desired beam position and easy integration into existing setups.

Newport

Newport (www.newport.com) will present the latest innovations from its family of photonic brands that include New Focus, Newport, Ophir, Spectra-Physics and Spiricon.

Booth highlights will include a variety of equipment. The Spectra-Physics Spirit is a compact industrial-grade ultrafast amplifier with software-adjustable repetition rates up to 1MHz, for micromachining of medical devices and other materials. The Spectra-Physics Pulseo 355-Turbo with advanced ultraviolet performance at very high repetition rates (up to 500kHz), a perfect solution for high-speed processing of semiconductors, touch screens, high density interconnects, and other microelectronics. The Spectra-Physics Explorer 1064-3 delivers high infrared peak power, excellent beam quality and brightness in a robust, compact package for memory repair and micromachining applications.

Raylase

Raylase (www.raylase.com), a manufacturer of high-precision components and subsystems for laser beam deflection, modulation and control, is presenting its Axialscan-12 at Lasys. The company's new AS-12 system allows fast and precise processing of multiple materials with very small spots. Speeds of up to 30 metres per second are possible using a dynamic z-axis, enabling the Axialscan-12 to be used in applications requiring flexible working areas and small focus diameters.

The Axialscan-12 is especially good at 3D-material processing. Raylase will be demonstrating its material position recognition system for marking a 3D, non-flat area, developed by its business unit System Solutions. Up to now, material position recognition has only been possible with two-axis systems. The Raylase system captures the object in 3D and can mark it regardless of its position.

Scanlab

Scanlab (www.scanlab.de) will present a wide range of galvanometer based scanning solutions for the photonics industry.

One of the show highlights will be the new dynAXIS 3 galvanometer scanner series. With integrated temperature regulation, these galvanometers produce extremely low drift for analogue position detectors.

Scanlab will also show the intelliSCANse 10 – a scan head with only 10mm aperture and high-end, high-resolution digital encoder galvanometer scanners. The basis for this innovation is the dynAXISse S which features a new encoder design with ultra low inertia and excellent dynamic performance.

Other highlights on show will be SCANalign, Scanlab's through-the-head machine vision solution which will help integrators build laser machines quickly and with greater ease, and laserDESK - Scanlab's laser processing software package.

All of these will be displayed during the show.

Workshop of Photonics

Lasys exhibitor Workshop of Photonics (www.wophotonics.com) will present its new polarisation converter at the show. Its unique property is damage threshold, which is much higher than alternative devices as it is fabricated inside bulk of UVFS glass. The S-waveplate is a super-structured waveplate that converts linear polarisation to radial or azimuthal polarisation. Radial polarisation enables focusing laser beam into smaller spot size (with high NA optics). Azimuth polarisation allows same metal machining properties in all directions. It is also applicable in optical tweezers, STED microscopy or other depletion applications. Standard S-waveplate models are available for 1030nm, 532nm, 800nm and 1550nm wavelengths. Custom wavelength converters are available on request.
