University of Michigan Unveils World's Most Powerful Laser

9/17/2025

Summary

Story summary

The ZEUS laser at the University of Michigan has reached a power output of 2 petawatts, making it the most powerful laser in the U.S.
Funded by the NSF, ZEUS aims to produce electron beams similar to those from large particle accelerators and invites global research teams for experiments.
A significant experiment simulating zettawatt-scale laser interactions is scheduled for later this year.
Australian tech brand Laser is transitioning to Lithium Iron Phosphate (LiFePO4) batteries for improved consumer safety, committing to this technology for all power banks by mid-next year.
Meta has created a laser-powered display prototype for augmented reality, offering ultra-bright, transparent screens, though production scaling poses challenges.

History

Historical Context

In 1917, Albert Einstein proposed stimulated emission, laying the groundwork for laser technology. Theodore Maiman developed the first working laser in 1960, marking a significant technological breakthrough. Today, advancements like the ZEUS laser at the University of Michigan, capable of 2 petawatts, continue to influence fields such as experimental physics and consumer electronics, showcasing the ongoing evolution of laser applications.
