Laserline will once again showcase its latest laser systems for joining and deposition welding at this year's Welding & Cutting show in Hall 5. This time the focus is on the world's first blue diode laser with an output power of 4 kW, which is said to have been developed for processing copper components.Its 445 nanometer wavelength is absorbed by copper and copper alloys, which is five t...
Recently, the Advanced Laser and Optoelectronic Functional Materials Department of the Shanghai Institute of Optics and Fine Mechanics, Chinese Academy of Sciences, has made progress in the research of Nd: ASL (Sr0.7Nd0.05La0.25Mg0.3Al22.7O19) laser crystals, and the related achievements were published in Infrared Physics&Technology under the title of "Tunable laser operations on Nd doped cont...
Reducing stray light is one of the main challenges in combustion experiments using laser beams (such as Raman spectroscopy) for detection. By using a combination of ultrafast laser pulses and gated ICCD or emICCD cameras, a time filter can be effectively used to remove bright and constant flame backgrounds. When the signal reaches the detector, these cameras can open electronic shutters within the...
The laser additive manufacturing technology of pure copper (Cu) with complex geometric shapes has opened up vast opportunities for the development of microelectronic and telecommunications functional devices. However, laser forming of high-density pure copper remains a challenge.Recently, the forefront of additive manufacturing technology has noticed a joint report by the University of Hong Kong, ...
According to a recent study published in the journal Science Advances, it reveals how early mammals grew and developed during critical periods of their long 'life history'. A research team including Queen Mary University of London used synchrotron X-ray tomography technology to image the growth rings in fossilized tooth roots, in order to infer the lifespan, growth rate, and even sexual maturity t...
