Recently, scientists used laser gyroscopes to measure that the change in Earth's rotational speed is less than one millionth. This technology can help scientists understand the complex flow of water and air, which can cause the smallest adjustments to the Earth's rotation.The Earth's rotation is not completely stable. Planets accelerate or slow down as they rotate, slightly shortening or prolongin...
BMW explained how to use WAAM (Arc Additive Manufacturing) starting from 2025 to manufacture lighter and stronger automotive components and reduce waste generation, in order to optimize the use of generative design tools.The demonstrated WAAM process uses aluminum wire raw materials directly deposited through laser welding heads, enabling automotive companies to manufacture lighter and more robust...
Streamlight, a leading supplier of high-performance lighting and weapon lights/laser aiming equipment, has launched upgraded models of its TLR RM 1 and TLR RM 2 series of lights, each now equipped with an HPL face cap, providing ultra bright beams of up to 1000 lumens and an extended range of up to 22000 candela.The popular TLR RM 1 and TLR RM 2 models are equipped with red or green lasers, both o...
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...
High power optical frequency combs play a crucial role in nonlinear precision spectroscopy, extreme ultraviolet optical frequency comb generation, nuclear atomic clock research, and other fields. Fiber optic femtosecond lasers are the preferred solution for achieving high power optical frequency combs due to their simple structure, stable performance, and easy amplification. However, due to the un...
