Attosecond X-ray analysis

Depiction of an ‘angular streaking’ scheme that enables the attosecond details of individual X-ray pulses to be read by a detector, akin to reading the face of a clock. Performed at the Linac Coherent Light Source in Stanford, US, ultrashort X-ray pulses photoionize neon while the circular polarization of an infrared laser field modulates the corresponding photoelectron energy and angle of the emission.

  • Observing ultrafast transient dynamics in optics is a challenging task. Two teams in Europe have now independently developed ‘optical oscilloscopes’ that can capture both amplitude and phase information of ultrafast optical signals. Their schemes yield new insights into the nonlinear physics that takes place inside optical fibres.
