Powerful laser experiments explore fusion energy

A former lead laser scientist details the intricate process of operating the Texas Petawatt laser, one of the nation's most powerful. The laser, used for research into stellar interiors and fusion energy, requires meticulous calibration and alignment. During a 'shot day,' scientists prepare targets like metal foil or gas jets for brief, high-energy pulses. These experiments aim to unlock scientific understanding in areas ranging from astrophysics to potential cancer treatments, despite the facility currently facing funding cuts.
