PRODUCT FOCUS: FIBRE LASERS FIBRE PROVIDERS A round-up of the latest fibre lasers for materials processing


Following the introduction of the LCG-3015AJ series of fibre laser cutting machines,AMADA has also released the high-speed ASF-EU automation storage system to complement the high dynamics of fibre technology. Offering fast cutting speeds, low running costs and the ability to cut copper, brass and titanium, the LCG-3015AJ series benefits from the addition of the new automated tower by providing constant ‘lights out’ processing. The ASF-EU was developed to


address the common concern that the higher cutting speeds and productivity of fibre lasers can be lost in the slow cycle times of available automation systems. The ASF-EU was designed to give the fastest sheet changeover times possible. The automated tower offers seven


raw material shelves and three finished product shelves, each capable of supporting a maximum load of 3,000kg. Raw material or finished parts can be loaded or unloaded without interrupting the cutting operation, ensuring maximum system uptime. www.amada.com


COHERENT has expanded the company’s fibre laser products with a new platform capable of delivering output powers of 4kW. The HighLight FL series employs Coherent’s modular architecture. This gives OEM customers and system integrators a choice of systems with turn-key operation, or modules to build their own custom fibre laser machines. The modular architecture, combined


with Coherent’s factory service training and qualification programme, means OEMs can benefit from Coherent’s


worldwide support infrastructure, and the option to offer service directly to their end customers. HighLight FL lasers at all power levels are available with a range of output delivery fibre options, optimised for cutting and welding a broad spectrum of metals and alloys. Coherent is a vertically integrated


manufacturer, incorporating its own laser diode pumps and active fibres for high performance, reliability and quality at a low cost of operation. The company’s worldwide logistics, applications development, and field integration teams ensure help is rapidly available in many regions around the globe. www.coherent.com


PHOTONIC SOLUTIONS offers fibre lasers and systems from world- leading manufacturers. The BlueCut femtosecond fibre laser from Menlo Systems implements the ‘Figure 9’ mode-locking technology to ensure reliability and stability in a compact, air-cooled package. The BlueCut is an industrial-grade microjoule laser system for micro-material processing, supplying sub-400fs pulses at 10µJ/10W. It gives variable repetition rates from single shot up to 10MHz. Also available from Photonic


Solutions are the Koheras systems from NKT Photonics, low noise, single frequency erbium and ytterbium doped fibre lasers. They offer line width in the hertz range in addition to high frequency stability and long coherence length. NKT also offers an OEM platform, the Koheras BasiK. This is currently deployed in interferometric applications such as seismic sensing for security, oil and gas exploration, and structural pipeline monitoring. Finally, the KKFL20 is a 1,064nm


continuous-wave fibre laser, the first of a new series of high performance fibre lasers from the HeCd laser

LASER COMPONENTS has introduced a thulium fibre laser from Keopsys. The CTFL fibre laser has an M²<1.1, a 1nm line width, and is available with wavelengths between 1,900nm and 2,050nm and an output power of 30W. The output is also randomly or linearly polarised, with a modulation option. As the laser is air-cooled, no


maintenance is needed. The laser is available in a benchtop, or in an OEM module that is easy to integrate. The high performance laser is an ideal


manufacturer Kimmon Koha. It has a very high polarisation ratio of 200:1 and rated power output of 20W. www.photonicsolutions.co.uk


ROFIN offers fibre lasers in a wide power range for marking, cutting, welding, drilling and surface treatment applications. In 2015, the laser specialist launched the third generation of its high-power fibre laser series (FL series), generating 2kW of laser power from one laser unit. The company has also released a 4kW version, the FL 040. Rofin FL series lasers are available


with power levels ranging from 500W to 8kW and supply the laser system market with two solutions. The first is lasers with direct spliced fibre of single-mode or multimode beam quality for direct integration into machines. The second is lasers with a fibre-to-fibre coupler or fibre-to-fibre switches of multimode beam qualities, which allow the user to plug up to four fibres for sequential or parallel beams. All lasers are equipped with the


Rofin Control Unit (RCU), which offers, besides numerous monitoring tasks, e-service capability as well as simple implementation of scanner-based applications. A five-step back reflection


tool for scientific research as well as polymer processing or OPO pumping. The Keopsys range of fibre lasers


also includes pulsed thulium, UV, green, CW Raman and erbium/ ytterbium fibre lasers (both CW and pulsed). www.lasercomponents.co.uk


resistance system allows reliable processing of highly reflective materials and protects the laser from damage. www.rofin.de


TRUMPF’S latest TruLaser 5030 Fibre system with TruDisk 8001 is an 8kW 2D laser machine. Its fibre-guided solid-state laser and highly dynamic drives enable the user to obtain maximum productivity across the entire sheet thickness spectrum; stainless steel at thicknesses up to 40mm are well within its scope. This is the ideal machine for mixed metal and multiple application production. The company’s BrightLine fibre


technology gives high quality cutting results. Users can change from thin


sheet processing to thick sheet processing on just one machine. On the TruLaser 5030 fibre 8kW, this capability is complemented by a range of functions, including CoolLine and PierceLine. Other new features are Smart Beam Control, a Condition Guide function, Smart Collision Prevention, and Drop and Cut. www.uk.trumpf.com
