Paul and colleagues: attosecond pulse train from high harmonics

Contribution grade

Optics and photonics · METHOD

Reference score170,000Provisional editorial estimate of this exact contribution; its grade is assessed separately.

What changed

Measured relative harmonic phases and inferred a phase-locked train of roughly 250-attosecond pulses.

Scientific scope

The record is the exact eight-author 2001 experiment and the pulse train reported there. It does not absorb isolated-attosecond-pulse demonstrations, every later metrology method or all high-harmonic source development.
