Laser Pulse Reveals Quantum Phase in Electrons

VIENNA, May 16, 2012 — Events that appear to happen instantaneously now can be resolved to a resolution of 10 attoseconds, enabling scientists to look at phenomena that happens on the order of attoseconds (10-18 s), previously far too fast to measure. Researchers at Vienna University of Technology's (TU Vienna) Photonics Institute fired short laser pulses at an atom. The waves of light pass through the atom, affecting its electric field. This causes the atom to ionize and lose an electron. The exact moment when the electron is removed from the atom is impossible to identify because the electron exists as a...Read full article
