Researchers used a "flying focus" laser pulse to overcome the dephasing limit in plasma accelerators, boosting electron energies to 396 MeV—more than twice the conventional limit over the same distance. The approach could enable much shorter, higher-energy particle accelerators, potentially reaching 100 GeV in under a meter. https://www.nature.com/articles/s41567-026-03352-x
