Fiber lasers are widely used in industry for various applications. For marking applications the most common types are pulsed fiber lasers with low average power (10-20 W), pulse lengths of 100 ns and pulse energy in 0,5-1 mJ range. However for applications of high speed ablations and cleaning of surfaces higher average power and pulse energy is needed to realize shorter production cycle times. For this purpose pulsed fiber lasers with morehockey17 h than 500 W average power and 50 mJ pulse energy have been developed to realize economic processes. In the long pulse range (μs to ms pulse length) QCW fiber lasers have been introduced that fulfil the demands of high pulse energy (up to 60 J) at lower average power (few 100 W range). These lasers fulfil the requirements that so far only lamp pumped Nd:YAG-lasers have been realized: high peak power and pulse energy with low average power in order to reduce investment costs for such devices. This presentation describes the latest development of such pulsed fiber lasers and their industrial applications and focuses in more details on drilling applications.

Surface treatment with high power pulsed fiber lasers gets more and more interesting to wide range of applications due to higher available average power and pulse energy. The average power is either increased by higher repetition rates or higher pulse energy. New laser concepts allow the parallel combining of several fiber laser modules up to an average power of several kilowatts. These lasers increase the efficiency of the processes by high removal rates. This paper gives an overview on the various applications of surface treatment such as cleaning of molds, depainting and surface preparation for welding and gluing. © 2014 IEEE.

For today's high volume production in the automotive industry, resistance spot welding and laser remote welding, while well established, present pro's and con's. For laser remote welding the main advantage is the significant cycle time reduction due to almost complete elimination of idle times and the advantages of laser welded seams. For resistance spot welding an advantage is the integrated clamping technology, which comes nearly for free. IPG Laser GmbH has combined these advantages in a new technology, offering the resistance spot welding process, featuring the simplicity of clamping tools and production facilities, used in combination with the advantages of laser welding.

The industrial applications of high-power fibre optic lasers include welding, 2D and 3D cutting, remote cutting and welding, brazing and surface treatments. The availability of fibre optic lasers with power outputs in excess of 10 kW might allow the development of novel fields of application in the welding of high thickness pieces: shipbuilding and offshore industries, pipe and cable manufacture and other heavy industry sectors. Carrying the beam by fibre optics allows high flexibility, even for the production of very large pieces, such as in the shipbuilding sector. This study describes the laser welding of high thickness pieces using a 30 kW laser and a 200 μm diameter fibre. On the one hand, such lasers allow a weld penetration depth of over 30 mm in a single pass, and very high process speeds for thinner materials on the other. Combining lasers with conventional arc welding techniques (hybrid welding) allows further optimization of weld quality and makes it possible to weld butt joints with a 'gap' of up to 1 mm. This paper presents the most recent results from very high-power fibre optic laser welding along with new applications in the manufacturing sector. © 2013 Copyright Taylor and Francis Group, LLC.

The world's most powerful laser system for industrial applications would be presented. Ytterbium fiber laser combines record 101.3 kW output power, CW operational mode and an excellent beam quality. Beam parameter product (BPP) does not exceed 16 mm × mrad, when we use 300 μm × 10 m feeding fiber, or near 25 mm × mrad, when fiber-to-fiber output coupler with 500 μm × 50 m process fiber is used. Emission wavelength is 1070 nm. High wall-plug efficiency 35.4%, compact laser cabinet and total weight less than 3600 kg open the new opportunities in different industrial and mobile applications. © 2014 IEEE.
