Laser-Based Ultrasound Finds Defects in Metal 3D Printing
LIVERMORE, Calif., May 2, 2022 — Researchers at Lawrence Livermore National Laboratory (LLNL) have developed an all-optical ultrasound technique capable of performing on-demand characterization of melt tracks and detecting formation of defects in the laser powder bed fusion (LPBF) metal 3D-printing process. The team proposed a diagnostic using surface acoustic waves (SAW), generated by laser-based ultrasound, that can reveal tiny surface and subsurface defects in LPBF metal 3D printing. The team reported that its
Fluence Opens Micromachining Facility
WARSAW, Poland, Nov. 23, 2021 — Femtosecond laser and fiber technology company Fluence has opened a facility in Wroclaw, Poland, called the Fluence Ultrafast Laser Application Laboratory (ULAL). The lab is equipped with a high-precision automated micromachining station based on...
Stanford Team Develops Self-Cooling Silica Fiber Laser
STANFORD, Calif., March 22, 2021 — A Stanford University research team developed a self-cooling laser based on a silica fiber architecture. By overcoming the need for external cooling, such as with a water-based cooling system, the design charts a course for future laser-based...
