I’ve fired one of America’s most powerful lasers—here’s what a shot day looks like

The Texas Petawatt Laser Facility at the University of Texas at Austin housed one of the most powerful lasers in the U.S., used for studying stellar interiors, fusion energy, and potential cancer treatments. Located underground, this laser could generate immense power, briefly surpassing the entire U.S. electrical grid. Scientists nationwide applied to use this facility, part of the Department of Energy’s LaserNetUS network, until it closed due to funding cuts. A typical “shot day” involved meticulous preparation and a brief, intense moment of experimentation. The facility’s closure highlights the challenges of maintaining advanced scientific research infrastructure. QUESTION: How might the closure of facilities like the Texas Petawatt Laser impact future scientific discoveries and innovations?
