Background IntroductionTwo dimensional materials have attracted widespread attention due to their atomic level thickness and unique properties, such as high binding energy, tunable bandgap, and new electronic degrees of freedom (valley electronics). They have many application prospects in fields such as microelectronics, nanophotonics, and nanoenergy. Various two-dimensional materials have their o...
Recently, according to a paper published in Nature Communications titled "Phonoenhanced nonlinearities in hexagonal boron nitride," engineers from Columbia University collaborated with theoretical experts from the Max Planck Institute of Material Structure and Dynamics to discover that pairing lasers with lattice vibrations can improve the nonlinear optical properties of layered two-dimensional ma...
In 2017, the detection of gravitational waves generated by the merger of binary neutron stars marked a significant breakthrough in physics. These waves reveal important information about the universe, from the origin of short gamma ray bursts to the formation of heavy elements.However, capturing gravitational waves from the merged residue remains a challenge as these waves avoid the detection rang...
The research from the University of West Virginia has been rewarded, as debris scattered in planetary orbits that pose a threat to spacecraft and satellites may be pushed away from potential collision paths by a coordinated space laser network.Hang Woon Lee, director of the Space Systems Operations Research Laboratory at the University of West Virginia, said that artificial debris dumps, including...
Image source: Federal Institute of Technology in Lausanne, SwitzerlandScience and Technology Daily, Beijing, September 27th (Reporter Zhang Jiaxin) Commercial femtosecond lasers are manufactured by placing optical components and their mounting bases on a substrate, which requires strict alignment of optical components. So, is it possible to manufacture femtosecond lasers entirely from glas...
