US Conducts Test of Record-Breaking High-Power Laser

Quick Summary

• Laser Achievement: The University of Michigan’s ZEUS laser system conducted its first experiment, achieving a power output of 2 petawatts (2 quadrillion watts). This is 100 times the planet’s electricity output but lasted only 25 quintillionths of a second.
• Technology: ZEUS uses techniques such as wakefield acceleration, where electrons accelerate behind laser pulses in plasma, achieving higher speeds due to the chamber’s configuration.
• Future Experiments: Plans include testing interactions between accelerating electrons and opposing laser pulses to simulate “zettawatt-equivalent” power effects, making a 3-petawatt laser appear one million times stronger.
• Cost & Design Benefits: Constructed for $16 million,ZEUS aims to replicate particle accelerator capabilities at reduced size and cost. Diffraction gratings safeguard against over-intensity during tests.
• Applications: Potential uses include improved imaging for soft tissues, cancer treatment advancements, gamma ray burst studies, black hole jet dynamics research, and other scientific investigations.
