Recently, the German research institution Fraunhofer ILT team is collaborating with the Department of Optical Systems Technology (TOS) at RWTH Aachen University to develop a testing system aimed at studying complex laser beam profiles using a new platform. This platform can construct customized beam profiles for laser powder melting (PBF-LB) 3D printing, thereby improving part quality, process sta...
A novel method is used to deflect the laser beam using only air. The interdisciplinary research team reported in the journal Nature Photonics that invisible gratings made solely of air not only do not suffer damage from lasers, but also retain the original quality of the beam. The researchers have applied for a patent for their method.Technology and PrinciplesThis innovative technology utilizes so...
Recently, a research team from the University of Massachusetts Amherst has pioneered a new technology that uses laser irradiation on concentric superlenses on chips to generate holograms, thereby achieving precise alignment of 3D semiconductor chips.This research result, published in the journal Nature Communications, is expected to not only reduce the production cost of 2D semiconductor chips, bu...
Recently, teachers and students from the Institute of Solid State Laser and Ultrafast Photonics at the School of Physics and Optoelectronic Engineering have made significant progress in the study of ultrafast carrier dynamics in optoelectronic functional crystals. The related research results are titled "Anisotropic carrier dynamics and laser fabricated luminosity patterns on oriented single cryst...
