The 3500W free output blue semiconductor laser beam is output in a free space manner, with a rectangular spot directly acting on the material surface without the need for fiber optics or laser processing heads. This laser has a wavelength of 455 ± 10nm, with continuously adjustable power and a maximum output power of over 3500W. It is mainly used for non-ferrous metal cladding, quenching, etc., to...
For example, the commonly used square shell battery cells for power batteries include laser welding of cover explosion-proof valves, laser welding of pole columns, and laser welding of cover plates and shells. During the process of laser welding of aluminum alloy, it is easy to generate unqualified phenomena such as explosion points, pores, welding cracks, excessive depth and width of fusion. ...
Recently, Li Hao and You Lixing's team from the Chinese Academy of Sciences Shanghai Institute of Microsystems and Information Technology developed an ultrahigh speed, photon number resolvable optical quantum detector with a maximum count rate of 5GHz and a photon number resolution of 61 by using the sandwich structure superconducting nanowires and multi wires working in parallel. The related rese...
Superlight Photonics, a start-up company headquartered in Enshurd, has developed a broadband laser chip that can replace the bulky and power consuming technology currently used in advanced imaging and metering equipment.This idea suddenly appeared in his mind, while moving his other belongings from Germany to his new home in Enschede. During his doctoral research at the Max Planck Institute of Mul...
Recently, Fujitsu and KDDI research company have successfully developed a high-capacity multi band wavelength multiplexing transmission technology using installed optical fibers.The new technology of the two companies can transmit wavelengths beyond the C-band by using batch wavelength conversion and multi band amplification technology.Expanding transmission capacity in remote areasTwo companies h...
