scale up in power with a diffraction-limited beam is an old one, with some pioneering work done at Lincoln Labo-ratory in the 1980s [1, 2]. Subsequent laser technology advances have allowed for practical implementations of those beam-combining concepts, and beam combining today is a well-accepted avenue for laser power scaling.

“Perform field welding only when called for on the plans and in accordance with 1072-20.” “Remove paint or galvanizing at the location of field welds by blast cleaning (SSPC SP-6 finish), or hand (SSPC SP-2 finish) or power tool cleaning (SSPC SP-3 finish) just prior to welding.
Laser beam welding (LBW) is defined as a welding process wherein coalescence is produced by the heat obtained from the application of a concentrated coherent light beam impinging upon the surface to be joined. Laser beam welding has many advantages: (1) it produces deep penetrating weld, (2) melting efficiency is very high ...
