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...
The team of Wu Dong, professor of the Micro/Nano Engineering Laboratory of University of Science and Technology of China, proposed a processing strategy of femtosecond laser two in one writing into multiple materials, manufactured a micromechanical joint composed of temperature sensitive hydrogel and metal nanoparticles, and then developed a multi joint humanoid micromachine with multiple deformat...
With the development of cutting-edge technologies such as automatic guidance and embodied intelligence, machine vision has put forward higher requirements for image acquisition, requiring precise recording of static images and the ability to sensitively capture dynamic changes in the scene. The existing dynamic and active pixel sensor technology integrates two functions: dynamic event detection an...
Recently, WEC Group, a leading engineering and manufacturing company in the UK, announced that it has completed the acquisition of Laser Profiles Ltd, a precision laser cutting leader in Bournemouth. For over 40 years, WEC Group has been providing manufacturing, laser cutting, precision machining, waterjet cutting, powder coating, and CCTV installation solutions.The company stated that the acqui...
German researchers have developed a method for controlling and manipulating optical signals by embedding liquid crystal layers into waveguides created by direct laser writing. This work has produced devices capable of electro-optic control of polarization, which may open up possibilities for chip based devices and complex photonic circuits based on femtosecond write waveguides.Researcher Alexandro...
