Topological laser (TL) is a laser device designed and manufactured using the principles of topological optics, which can produce a robust single-mode laser and is an ideal light source for future new optoelectronic integrated chips. Electrically pumped topology lasers have become a research hotspot due to their small size and ease of integration, but topology lasers based on electrical injection a...
On quartz sheets, the angular rhombic boron nitride crystals with a thickness of only 1 to 3 microns are as thin as cicada wings, but their energy efficiency is 100 to 10000 times higher than traditional optical crystals. At the opening ceremony of the 2024 Zhongguancun Forum Annual Conference held on April 25th, the world's thinnest known optical crystal was listed as one of the top ten technolog...
Zygo Corporation, a business unit of AMETEK, announced that it will be showcased at the D28 booth of the Space Comm Expo held in Farnborough, UK from March 6th to 7th this year.Space Comm showcases the end-to-end supply chain of products, services, and applications that provide information and technological development for commercial aerospace enterprises, governments, and defense organizations, p...
Starting from June 20th, The Creativity Falcon 2 laser cutting machine will also be launched in Germany, equipped with a new 60W laser head. With this ability, fully encapsulated equipment can now also be carved into steel. High power is achieved through twelve 5-watt laser diodes, whose beams are combined with each other. This will make it possible to cut 22mm thick lime wood and 30mm thick or...
Recently, a team led by Gao Chunqing and Fu Shiyao from the School of Optoelectronics at Beijing University of Technology combined optical spatial coordinate transformation with photon spin Hall effect to construct a photon angular momentum filter for the first time internationally, achieving on-demand regulation of photon spin angular momentum and orbital angular momentum.The related achievements...
