X-ray Pulse

This art represents a coherent (laser-like) X-ray pulse with the largest color spread generated to date. Such rainbows of color can support extremely short, few-attosecond light pulses, which are invisible to the human eye but important for capturing the ultrafast dynamics in materials and nanosystems. —Tenio Popmintchev, JILA, University of Colorado at Boulder
