A research team led by Lawrence Berkeley National Laboratory (Berkeley Lab), Columbia University, and Autonomous University of Madrid has successfully developed a novel optical computing material using photon avalanche nanoparticles. This breakthrough achievement was recently published in the journal Nature Photonics, paving the way for the manufacture of optical memory and transistors at the nano...
Ruifeng Picosecond laser: Open the door to the art of cutting resin eye lensesAs an important innovation in the modern eyewear industry, resin lenses bring us visual clarity and comfort with their lightness, transparency and impact resistance.However, with the continuous improvement of people's demand for quality and personalization, how to achieve accurate and beautiful cutting on resin eye lense...
As is well known, food and beverage product manufacturers have strict requirements in ensuring the hygiene and cleanliness of their equipment. Once these devices and components are designed or manufactured improperly, they are likely to cause pollution, ultimately leading to health hazards, brand reputation damage, and expensive recall actions. The shortage of labor and raw materials further exace...
The deformable mirror used in adaptive optics can instantly correct the static wavefront aberrations and atmospheric turbulence wavefront disturbances of the optical system by changing its surface. This enables the optical system to automatically adapt to changes in the environment and maintain optimal performance. It is widely used in high-resolution astronomical observations, laser atmospheric t...
Virtual and Physical Prototypes: X-ray laser direct writing 3D nanolithography.Multi-photon polymerization (MPP), also known as 3D nanoprinting, has been investigated using wavelength-tunable femtosecond lasers. At a fixed pulse width of 100 fs, any spectral color in the range of 500nm to 1200nm can be used, which reveals the interaction of more subtle photophysical mechanisms than two-photon phot...
