The current deep neural network system (such as ChatGPT) can quickly improve energy efficiency by 100 times in training, and "future improvements will greatly increase by several orders of magnitude. Scientists from MIT and other institutions have demonstrated a new optical neural network training method that can crush state-of-the-art electronic microprocessors.Moreover, the computational density...
Application backgroundLaser swing welding technology was born out of the urgent demand for welding quality and efficiency in modern manufacturing industry. Traditional welding technology has shortcomings in precision, strength, and complex structures, which has led to the rapid application of laser welding in various fields. However, it still has defects such as pores and cracks, and has limitatio...
At the UpakExpo 2024 exhibition to be held in Moscow at the end of January, Chinese company Golden Laser will showcase for the first time two laser die-cutting machines focused on the printing, labeling, and packaging markets in Russia.The Golden Laser LC350 is a web machine designed to handle labels printed on digital and flexographic printing machines. It can cut, die cut, and kiss cut paper, pl...
When observing biological samples under a microscope, if the medium in which the objective lens is located is different from the sample, the light beam will be interfered with. For example, when observing a water sample with a lens surrounded by air, the light bends more strongly in the air around the lens than in water.This interference can cause the measured sample depth to be smaller than the a...
Recently, a research team from the Astronomical Glaciology Laboratory under the RIKEN Nishina Center (RNC) of the Japanese Institute of Physics and Chemistry announced that they have developed a new laser based sampling system for studying the composition of glacier ice cores.The above image shows the discrete holes sampled 150mm from the shallow ice core of the Fuji Ice Dome in Japan (Southeast ...
