It is reported that researchers from the University of Salamanca in Spain have demonstrated a high-order harmonic spectroscopy scheme generated by the interaction between a structured driving beam and a crystal solid target. This work promotes the topological analysis of high-order harmonic fields as a spectroscopic tool to reveal nonlinearity in the coupling of light and target symmetry. The rele...
Recently, physicists from the University of Bath in the UK have developed a new generation of specialized optical fibers to address the data transmission challenges of the future quantum computing era. This achievement is expected to promote the expansion of large-scale quantum networks. The research results were published in the latest issue of Applied Physics Letters Quantum.The highly anticipat...
Photography brand Leica has launched its first 4K movie and television. The Leica Cine 1 laser TV was announced a year later during the I FA 2022 period. This iconic photography brand is shifting some of its focus to projecting perfect images in our living room.featureThe Leica Cine 1 laser TV embodies Leica's philosophy in its camera design. Leica continues to provide precision optical engineerin...
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...
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...
