Company: 

Brimo Technology

Brimo Technology, a fibre laser source manufacturer based in Taiwan, will show its nanosecond-pulse (MOPA) laser sources. The product offers 10-50W power, a wavelength of 1,064nm, pulse width modulation of 25ns to 250ns, a frequency modulation of 30kHz to 500kHz, an M2 of less than 1.5, and power stability of less than 5 per cent.

The company also provides control cards, software, F-theta lenses, galvo scanners, and other industrial components.

Ekspla

Ekspla will introduce a picosecond high power UV laser. The Atlantic UV30 laser delivers 30W of output power at 355nm.

In industrial markets, increased reliability of high power and UV components is critical. The Atlantic UV30 optical layout was optimised for longevity and stable operation in the UV range. As a result, 8,000 hours UV optics lifetime is guaranteed.

Short, 10ps pulse duration minimises the heat-affected zone. Due to the high 75µJ pulse energy and UV output, the laser can be adapted for tough processes, like OLED cutting, sapphire processing, and ceramics micromachining.

Thanks to a negligible output beam spatial characteristic change over a wide output power range, the same Atlantic UV30 system can be used in numerous operation modes and for processing various materials. Up to 1MHz repetition rate enables this laser to be used for high throughput material processing.

Company: 

Foba

Foba will present its patent-pending innovation in vision-based automated laser positioning. A software update enables the precise alignment of laser marks, even relative to products that are positioned unexpectedly within the marking field. This will be demonstrated on a Foba M1000 marking station to show that expensive part fixtures are in many instances unnecessary.

Another marking station on site will be the Foba M2000-P, equipped with the Y.0201-DN fibre laser, which is designed for paint removal on plastics for day-night applications. Additionally, Foba will showcase its powerful fibre laser marking system Y.1000, a 100W laser marker for integration into high-speed processing lines and for the application of robust marks on high-wear parts.

Two of Foba’s laser marking specialists will hold lectures on 5 June: ‘Fixtureless laser marking’ by Faycal Benayad-Cherif, and ‘UDI laser marking on medical devices’ by Christian Söhner.

Company: 

Laser Components

Laser Components will be exhibiting its high-power triple laser mirrors. Triple mirrors are designed for frequency multiplying lasers, for example in Nd:YAG laser systems that emit at the fundamental wavelength of 1,064nm and have harmonics at 532nm and 355nm. Here, a high degree of reflectivity at each of these wavelengths is required.

Traditionally these coatings were applied in two separate runs, for example a coating for 1,064nm and 532nm was first applied, followed by a coating for 355nm. Consequently, production of triple mirrors was time consuming and costly.

Laser Components has developed a new coating method whereby triple mirrors can be produced in a single coating run. Not only does this reduce production time, and thus the unit cost, but also yields a higher spectral performance than previous production techniques. This method means triple mirrors can be made with custom wavelength combinations to suit any application.

Lasermet

Lasermet will be displaying its Laser Castle safety cabin, a certified, modular, rapid-build solution for maintaining safety around the multi-kilowatt lasers.

This sturdy cabin – built to any size with modular components – can safely withstand a 5kW laser for many minutes. For higher powers (6kW upwards), the active laser guarding product Laser Jailer and Glaser Jailer active filter windows will instantly switch off the laser if the interior of the cabin is struck by the beam.

The full dual-channel laser interlock controller, with touch screen interface, is designed for automation integration. It keeps the user safe from laser radiation by ensuring the laser can only be operated when all interlock switches are safe.

Users can choose a door configuration, and optional Swallow fume extraction system with active windows or HDCCTV.

In addition, Carbide brings in new technologies featuring high average output power and wall plug efficiency. It also has a novel approach to a cavity design, which allows volume production optimisation and fast laser warm-up time, important for medical applications.

An intra-cavity pulse picker reduces the laser cost and power consumption. Carbide lasers feature a number of options complementing requirements of various applications: certified safety shutter, beam conditioning unit, automated attenuator, harmonics generators, and additional pulse picker for enhanced contrast.

Combined with Light Conversion‘s wavelength converters – harmonics generators and parametric amplifiers – and ultrafast Harpia spectrometers, Carbide lasers become a powerful tool for scientists.

Company: 

Northrop Grumman Synoptics

Northrop Grumman Synoptics will be exhibiting at the event. The company produces large single crystal fluoride materials for Faraday rotator or isolator applications. These materials exhibit small nonlinear refractive index and thermo-optic coefficients, while maintaining Verdet constants near those of the commonly used terbium gallium garnet (TGG) crystals. In particular, the cubic potassium terbium fluoride (KTF) crystal has low absorption and thermo-optic coefficients.

Synoptics’ current capabilities in the manufacture of high quality TGG and the advancements in the growth of other crystalline materials, such as KTF, will lead to improved optical isolation performance for higher power lasers. Recently measured thermo-optic coefficients for KTF and product testing show that these fluoride materials have very promising characteristics.
