Recently, the research team of the Aerospace Laser Technology and System Department of the Shanghai Institute of Optics and Fine Mechanics, Chinese Academy of Sciences, reported for the first time a low repetition frequency full polarization maintaining 9-shaped cavity fiber laser at 915 nm. The relevant research results were published in Optics Express under the title "Low repetition rate 915 nm ...
Recently, scientists from the National Ignition Facility at Lawrence Livermore National Laboratory in California produced a burst of energy by bombarding hydrogen pellets with 192 laser beams, briefly reproducing the fusion process that powers the sun. This is a repeat of an experiment in December last year, but this time the scientists generated more energy, with a gain almost double that of the ...
The laser driven particle accelerator on silicon chips was created by two independent research groups. With further improvements, this dielectric laser accelerator can be used in medicine and industry, and even in high-energy particle physics experiments.Accelerating electrons to high energy is usually accomplished over long distances in large and expensive facilities. For example, the electron ac...
Recently, Longi Green Energy Technology Co., Ltd. (hereinafter referred to as "Longi"), as the first unit, published a research paper titled "Silicon heterojunction back contact solar cells by laser patterning" online in the journal Nature, reporting for the first time the research results of breaking through 27% of the photoelectric conversion efficiency of crystalline silicon cells through full ...
According to relevant media reports, a research team from the Helmholtz Center in Berlin, Germany, and Humboldt University has jointly developed a new type of perovskite stacked battery. This battery has broken the world record for similar batteries with a photoelectric conversion efficiency of 24.6%. In the solar cell family, in addition to silicon-based solar cells, there are also thin-film so...
