science 🔬 Cheaper, smaller lasers are on the way ⚛️
Researchers successfully operated a laser-plasma free-electron laser in a stable, high-gain regime for the first time. This breakthrough occurred at Helmholtz-Zentrum Dresden-Rossendorf (HZDR) and Synchrotron SOLEIL near Paris. The team generated 272 nanometer ultraviolet light flashes with high pulse energy on an unspecified date. This development drastically reduces the required size compared to conventional facilities by a factor of about a thousand. Future work aims to optimize the process for extreme ultraviolet light (EUV) applications.
