Laser material processing has been widely used in advanced industries, ranging from designing and producing lightweight, ultra wear-resistant parts and equipment with complex geometric shapes to repairing damaged or worn components through technologies such as 3D printing of deposited metal powders or deposits.Use laser pulses for surface treatment to prevent fatigue. But the impact of such techno...
LiDAR sensors are crucial for implementing modern technologies such as autonomous driving, AR/VR, and advanced driving assistance systems. For example, more accurate shape detection in AR/VR devices and smartphones depends on the improved range resolution of medium and short range LiDAR. This requires a single photon detector with improved timing jitter performance.LiDAR calculates the distance an...
As a breakthrough leap in scientific exploration, the new generation of powerful X-ray lasers is now targeting the fastest and most basic processes in nature. Their mission: to uncover the complex atomic arrangement that drives these phenomena, providing unprecedented insights into chemical reactions, electronic behavior in materials, and the mysteries of the natural world.Unlocking the precise me...
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...
Recently, the Los Alamos National Laboratory (LANL) in the United States has developed a method for quantum light emitters, which stacks two different atomic thin materials together to achieve a light source that generates circularly polarized single photon streams. These light sources can also be used for various quantum information and communication applications.According to Han Htoon, a researc...
