Compact All-Attosecond Spectroscopy

OPN Staff

A lab-scale approach creates attosecond pump and probe pulses from a commercial infrared laser.

The 2023 Nobel Prize in physics honored pioneers of methods to create attosecond (10–18 s) pulses, which spawned a new field: attochemistry. Most attosecond pump–probe experiments, however, use an extreme-ultraviolet (XUV) attosecond pulse as the pump and an intense near-infrared (NIR) femtosecond pulse as the probe. Ideally, scientists would like to leverage more precise attosecond-pump/attosecond-probe spectroscopy (APAPS)—but these experiments have usually taken place only at dedicated free-electron laser facilities or in other large-footprint schemes.
