"paradigm shift... 500 W, single-mode, continuous-wave 532 nm... eliminates risk to integrity of single crystal by combining seven lasers... copper additive manufacturing... chip-to-wafer welding, combines power and modulation capabilities... future: coupling frequency-doubled, single-mode-infrared laser modules with coherent beam combining enabling high CW power in laser machining processes for the first time"
