Limits RegistryResearchers at the Center for Relativistic Laser Science (CoReLS) in South Korea focused a petawatt-class laser to an intensity of about 1.1 x 10^23 W/cm² in 2021, verified via the ponderomotive scattering of electrons — a new laboratory record for focused light intensity, roughly a trillion trillion times brighter than sunlight on Earth's surface.
The question, scope, and sources behind this Registry record.
Researchers at the Center for Relativistic Laser Science (CoReLS) in South Korea focused a petawatt-class laser to an intensity of about 1.1 x 10^23 W/cm² in 2021, verified via the ponderomotive scattering of electrons — a new laboratory record for focused light intensity, roughly a trillion trillion times brighter than sunlight on Earth's surface.
The highest laser light intensity ever achieved at a focal spot in a laboratory, measured as power per unit area at peak pulse power.
Change a parameter to stress-test whether a proposed result is still inside the published specification. This is an audit aid, not a proof checker.
This record has no editable parameters. Read the formal question and assumptions before challenging it.
Current frontiers derived from accepted Claims.
An observed or demonstrated result; no opposing bound is implied.
The frontier is not sacred
Most progress starts with a disagreement that survives contact with evidence. If you can push the known lower bound up or pull the upper bound down, show us the work.
≥ when you have shown that at least this value is achievable.≤ when you have shown that anything above this value is impossible.No vibes. State the value, define the scope, and link the paper, proof, code, or reproduction that lets another person check it. Editors review every challenge before the public record changes.
