In EU project ALBATROSS, Fraunhofer IWS has developed battery housing for E-vehicles.Laser processes with dynamic beam shaping create stable joints even in challenging material combinations. Recent applications demonstrate how to eliminate filler materials while improving quality, energy efficiency, and production logic.Fraunhofer Institute for Material and Beam Technology (IWS) will present novel...
Researchers from the University of Aveiro in Portugal and the School of Engineering at Porto Institute of Technology (ISEP) in Portugal reported a study on the influence of laser beam intensity distribution on the geometric shape and process stability of lock holes under green laser radiation. The relevant paper titled "Influence of Laser Beam Intensity Distribution on Keyhole Geometry and Process...
Strong field quantum optics is a rapidly emerging research topic that integrates nonlinear optoelectronic emission elements rooted in strong field physics with the mature field of quantum optics. Although the distribution of light particles (i.e. photons) has been widely recorded in both classical and non classical light sources, the impact of this distribution on the photoelectric emission proces...
With funding from the National Science Foundation of the United States, researchers at the University of Rochester are developing photonic chips that use quantum technology called "weak value amplification" to replace mechanical gyroscopes used in drones, enabling them to fly in areas where GPS signals are obstructed or unavailable.Using this quantum technology, scientists aim to provide the same ...
