Recently, Hu Lili, a research group of the Advanced Laser and Optoelectronic Functional Materials Department of the Shanghai Institute of Optics and Fine Mechanics, Chinese Academy of Sciences, proposed a new scheme based on rare earth ions Dy3+doped quartz glass as a yellow laser material, and the relevant research results were published in the Journal of the American Ceramic Society as "Effect o...
Driven by the pioneering work of scientists such as John Young Hall, significant progress has been made in precision measurement in the field of laser physics. His contribution to laser frequency stability and precise measurement using lasers has led to groundbreaking techniques that significantly reduce residual amplitude modulation.John Hall's research focuses on understanding and manipulating s...
A team of computer and electrical engineers at UC Santa Barbara, in collaboration with several colleagues at Caltech and another colleague at Anello Photonics, has developed a first-of-its-kind chip that can carry both laser and photonic waveguides. In a paper published in the journal Nature, the team describes how they made the chip and how it worked during testing.With the advent of integrated c...
Physicists have been working hard to improve the accuracy of atomic clocks, which are the most precise timing devices currently available. A promising way to achieve higher accuracy is to utilize spin squeezed states in clock atoms.Spin squeezed states are entangled quantum states in which particles work together to counteract their inherent quantum noise. These states provide incredible potential...
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...
