Recently, the research team of the High Power Laser Element Technology and Engineering Department of the Shanghai Institute of Optics and Mechanics, Chinese Academy of Sciences, has made new progress in the study of improving the damage threshold of fused quartz elements through laser cleaning. The study proposes for the first time the use of microsecond pulse CO2 laser cleaning to enhance the dam...
Tunoptix, a developer of computational meta-optics, based in Seattle, WA, has made what it calls “a breakthrough in mobile-scale spectral imaging”. The company’s latest meta-optical platform captures high-fidelity spectral signatures across the visible-to-NIR spectrum in a compact form factor smaller than 1 cm3, consuming less than 500 mW, and operating at real-time frame rates.Tunoptix’s ultra-c...
Recently, the latest research report from FLEET, an interdisciplinary research team in Australia, revealed a significant leap in laser technology, achieving unprecedented levels of spectral purity.Spectral purity, which refers to the degree of matching of a single light frequency (or color) generated by a laser, is an important indicator for measuring laser performance. By using a scanning Fabry P...
Recently, SMART Photonics, a Dutch photonic integrated circuit manufacturer, announced a major decision to transfer its entire production capacity from 3-inch wafers to 4-inch silicon substrates, thereby expanding the production scale of photonic chips and significantly reducing chip prices.According to the company, SMART Photonics is one of the first photonic integrated circuit foundries to provi...
Recently, Yang Shanglu, a researcher at the Laser Intelligent Manufacturing Technology Research and Development Center of Shanghai Institute of Optics and Fine Mechanics, Chinese Academy of Sciences, has made new progress in laser welding of the fourth-generation reactor-molten salt reactor structural material Ni-28W-6Cr nickel-based superalloy.The research team applied the high power fiber ...
