By Vjaceslav Avilov, André Schneider, Marco Lammers, Andrey Gumenyuk, Michael Rethmeier A well-known problem of partial penetration laser beam welding is keyhole-tip instability representing the main source of porosity – gas bubbles leave the keyhole near its tip. The second important problem of keyhole mode laser welding is very intensive thermocapillary (Marangoni) convection in the upper […]

By I. Miyamoto, Y. Okamoto, A. Hansen, T. Amberla, J. Vihinen, J. Kangastupa Silicon/glass is one of the most widely used material combinations for sensing and actuating microsystems and micro electronic technologies. Anodic bonding has been most widely used for Si/glass bonding since its invention in 1969, because of its excellent mechanical properties and process […]
The Difference Between Fiber Lasers and Fiber Delivered Lasers
By Tony Hoult Nobody would disagree that real change is occurring in the laser industry. In the broadest context, what is happening is a shift from the conventional technique of assembling lasers using free space optical components to a technique based on splicing together fiber based components. It is now very widely accepted that this […]
