Powerful Lasers Reveal How Matter Becomes Plasma in Trillionths of a Second

Ultrafast lasers tracked plasma formation and ionization in copper with picosecond precision. Results show rapid ion growth ...

Copper blasted into a million-degree plasma strips away 22 electrons in a flash before atoms recover

When laser flashes hit matter, electrons are knocked off their orbits around the atomic nuclei. This can generate extremely hot plasmas composed of charged particles—ions and electrons. Researchers at ...
