Summary

  • University of Michigan’s Zettawatt-Equivalent Ultrashort pulse laser System (ZEUS) is now the most powerful in the US.
  • During its first experimental use, it generated 2 quadrillion watts, but the pulse only lasted 25 quintillionths of a second.
  • The laser is aimed to be used for experiments across medicine, physics, and materials science, for example, creating plasma by hitting helium atoms.
  • Powered by infrared light pumped up by additional lasers, it is designed to be focused on a target the size of a cell so the university plans to increase its intensity to 3 petawatts.
  • While this is the most powerful laser in the US, Europe’s ELI-NP laboratory reaches up to 10 petawatts.
