By Oleg Raykis Today there exist a number of technologies for additive manufacturing of components. The two most prominent types utilizing lasers for generating parts out of metals are either powder bed based solutions or direct energy deposition, often referred to as laser metal deposition. As a company Laserline focuses mainly on the second type. […]

Laser Micro Welding of Aluminum with the Superposition of a Pulsed Diode Laser and a Pulsed Nd:Yag Laser
By Philipp von Witzendorff, Lorenz Gehrmann, Martin Bielenin, Jean-Pierre Bergmann, Stefan Kaierle and Ludger Overmeyer Pulsed laser welding is applied for welding of thin aluminum sheets when the heat affected zone has to be minimized. The pulsed laser process enables a low and precise heat input because the heat dissipates away in between the laser pulses. […]

Wide Operational Range Pulsed Fiber Laser for Processing Thin Film Photovoltaic Panels
By: Shinobu Tamaoki Sumitomo Electric Inc. Pulse fiber lasers (PFL) have become widely popular for micro-machining applications due to their many benefits, such as the high beam quality, compactness, high wall-plug efficiency, and reliability. MOPA (Master Oscillator Power Amplifier) architectures, which provide temporal pulse shape control, are particularly interesting.
