A team of researchers in Berkeley Lab's Accelerator Technology and Applied Physics (ATAP) division has developed a new technique that combines fiber lasers of different wavelengths to generate ultra-short laser pulses. The research is in the journal Optics Letters.This work could advance the development of laser plasma accelerators (LPA), which have the potential to push the frontiers of high-en...
The latest research led by the University of Surrey shows that alumina (Al2O3) nanoparticles can significantly enhance the lifespan and stability of perovskite solar cells, extending the service life of such high-efficiency energy devices tenfold.Although perovskite solar cells have advantages such as low cost and light weight compared to traditional silicon-based technologies, their commercial po...
Leica Geosystems, a subsidiary of Hexagon, has developed Leica BLK2GO PULSE, its first person laser scanner, which combines LiDAR sensor technology with the original Leica BLK2GO shape. The technology will be released in early 2024.The scanner provides users with a fast, simple, and intuitive first person scanning method that can be controlled through a smartphone and provides real-time full color...
