Silicon micromirrors can guide laser beams at extremely high speeds, allowing operators to dose heat input to workpieces with absolute precision. But to date they have not been robust enough to be ...

Yongcui Mi has developed a new technology that enables real-time shaping and control of laser beams for laser welding and directed energy deposition using laser and wire. The innovation is based on ...

Piezo ceramic actuators combine rapid response with high resolution and high force generation, ideal prerequisites to drive highly-dynamic deformable mirrors. The principle has been used in adaptive ...
