Laser cladding, also known as laser metal deposition, is a process of depositing one material onto another.When the laser beam scans the target surface, metal powder or wire flow is fed into the molten pool formed by the laser beam, thereby producing the required material coating.The laser cladding method improves the surface properties of the parts, such as wear resistance, and allows for the rep...
One of the laser leaders in the field of life sciences, Coherent Gao Yi (New York Stock Exchange: COHR), recently announced that its Axon laser won the 2023 Business Innovation Award at the awards ceremony held by the British Physical Society on October 30th.Dr. Vincent D.

Hybrid 3D integrated optical transceiver. (A, B) Test setup: Place the photon chip (PIC) on the circuit board (green), and glue the electronic chip (EIC) onto the top of the photon chip. (C) It is the cross-section of the EIC-PIC component with micro protrusions. (D) Display the mesh of the finite element model.The latest progress in artificial intelligence, more specifically, is the pressure plac...
As humanity enters a new era of computing, new small tools are needed to enhance the interaction between photons and electrons, and integrate electrical and photon functions at the nanoscale. Researchers have created a novel III-V semiconductor nanocavity that can limit light below the so-called diffraction limit, which is an important step towards achieving this goal.In the journal Optical Materi...
