Enhanced laser heterodyne spectroscopy contributes to the measurement of atmospheric greenhouse gases

At the Fraunhofer Institute for Laser Technology (ILT), researchers in collaboration with RWTH Aachen University – Chair for Technology of Optical Systems (RWTH-TOS) are using a spatial light modulator (SLM) to shape the beam of an ultrashort pulse laser precisely into the desired pattern to apply to the surface of a workpiece.The developers say that this approach “significantly speeds up processi...

Quantum photonics is one of the important research directions in the quantum field, which utilizes the unique properties of light at the quantum level. The core of this field is the deterministic single photon source, which sequentially emits individual photons through spontaneous emission and is the cornerstone of quantum communication, computing, and secure encryption. However, under environment...

Headdisplay devices such as Apple Vision Pro, Meta Quest, and PICO are expected to completely change the way we perceive and interact with various digital information. By providing more direct interaction with digital information, MR has become one of the key driving forces for the metaverse, spatial computing, and digital twins, and has begun to be widely applied in fields such as intelligent tou...

Vast's Haven-1 program will become the world's first commercial space station, equipped with SpaceX's Starlink laser terminal, providing connections to its crew users, internal payload racks, external cameras, and instruments at speeds of gigabits per second and low latency.Max Haot, CEO of Vast, said: "If you need to provide high-speed, low latency, and continuous Internet connection on the orbit...

Recently, a team of Professor Ruan Shuangchen and Professor Zhou Cangtao from Shenzhen University of Technology proposed for the first time internationally a physical solution based on the generation of attosecond pulses and subperiodic coherent light shock radiation from a superluminal plasma wake field, and explained a new coherent radiation generation mechanism dominated by collective electron ...
