Attosecond science

Application note Atto

The process of high-harmonic generation (HHG) is the key when it comes to generating isolated attosecond pulses [1]. This coherent extreme-ultraviolet radiation has become a valuable tool to resolve ultrafast motion in atoms and molecules [2, 3]. However, low data-acquisition rates imposed by low repetition-rate laser systems hamper the advancement of these sophisticated experiments. Consequently, the availability of high repetition-rate sources has overcome a major obstacle in this young field [4].

Our fiber-based laser sources excel in terms of pulse energy at repetition rates in the ~100kHz to multi-MHz range thus enabling fast acquisition rates. Furthermore, our low carrier-envelope phase noise addons enable the generation of isolated atto-second pulses.

AFS offers different chirped-pulse amplification systems to run your beamline: compact Yb systems, high-power Yb systems or even Tm-based systems emitting at ~2µm. They can then be extended by flexible nonlinear compression addons and a subsequent high-harmonic generation to provide a turnkey driving system for your attosecond beamline.
