Conservation of energy is a fundamental concept in physics that can be used to explain anything from planetary orbits to the internal workings of individual atoms.Energy can be converted into other forms, but the overall energy level is usually considered to vary over time. Therefore, when attempting to describe a system, physicists usually pay attention to ensuring that it is isolated from the su...
Recently, Amada weld tech Inc., a Japanese supplier of welding and cutting solutions, grandly launched a new wl-300a precision laser welding workstation, which is equipped with advanced continuous wave (CW) or quasi continuous wave (QCW) fiber lasers. It has a wide range of applications, especially for metal welding and processing of selected plastic materials, especially in the aerospace field.Wl...
An international research team from Leibniz University in Hanover and Strathclyde University in Glasgow overturned the previous hypothesis about the influence of multiphoton components in the thermal field and the interference effect of parameterized single photons. The journal Physical Review Letters published the team's research."We have demonstrated through experiments that the interference eff...
The China International Industrial Expo is an important window and economic and trade exchange and cooperation platform for China's industrial sector to the world, as well as a window for the world to understand the current development status of China's manufacturing industry. It is understood that the scale, energy level, and number of new exhibits of this year's Industrial Expo are all the highe...
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 field strength optimization of Er doped silicate fiber as an extended L-band broadband amplifier. Relevant research achievements were published in Optics Letters under the tit...
