In article number 2000433, Maxime Chambonneau, Qingfeng Li, Stefan Nolte, and co‐workers demonstrate semiconductor–metal ultrafast laser welding—an additive manufacturing technique limited to other material families so far. This achievement is made possible by the determination and the precompensation of the nonlinear focal shift in the filamentation regime. This work offers new insights for the fabrication of microelectronic devices.

超快激光焊接：驯服超快激光灯丝以优化半导体-金属焊接（激光光子技术，修订版15（2）/ 2021）

Maxime Chambonneau，Li Qingfeng，Stefan Nolte及其同事在编号2000433中的演示了半导体-金属超快激光焊接，这是迄今为止仅限于其他材料系列的增材制造技术。通过确定和预补偿丝状状态中的非线性焦点偏移，可以实现此目标。这项工作为微电子器件的制造提供了新的见解。
