A Shorter Pulse Climbed Higher Before Coherence Broke
Changing pulse duration and intensity selected different electron pathways and extended extreme-ultraviolet emission in an insulator.
Summary
Changing pulse duration and intensity selected different electron pathways and extended extreme-ultraviolet emission in an insulator.
Experiments tuned laser pulses from 5 to 29 femtoseconds and intensities from 0.8 to 74 terawatts per square centimeter. Moderate many-cycle pulses accumulated carriers across cycles, while few-cycle pulses near 22 terawatts per square centimeter drove subcycle multiband motion reaching 25 to 50 electron-volt photons before decoherence suppressed emission. The result is a materials-and-optics control study, not a finished light source.
Why it matters
