Users of intense lasers rely on several methods and devices to characterize a laser short pulse before the experiments.

However, even if all these methods and devices are implemented, it is still very difficult to assess the suitability of the pulse characteristics for the interaction with a plasma since:

  • the laser pulse must be prepared / transformed for the characterization
  • the characterization is made before the interaction chamber
  • the devices have limited precisions
  • the interplay between each pulse characteristic and the plasma is not fully clarified

Calibrated ion spectrum obtained with SL-KAIO (C+: blue, Proton: green)

TNSA: a mechanism sensitive to energy, duration, and spot size

Acceleration of ions from a contaminant layer by TNSA mechanism, mediated by  hot electrons from laser-thin foil interaction

  • TNSA is very sensitive to the laser intensity (hence to energy, duration, waist, contrast) onto the thin foil. Proton acceleration by TNSA  is an excellent candidate to assess if a laser should be used for interaction.
  • SourceLAB developed a new versatile device, KAIO, based on TNSA protons, that gives unambiguous and quantitative indications on the suitability of a pulse for the interaction with a plasma, and how to improve it.
  • Beyond assessing the suitability of a laser pulse to laser plasma interaction experiments, KAIO is a unique laser ion accelerator that delivers beams that gives access to applications such as proton radiography, Proton Induced X-ray Emission (PIXE), biological dosimetry.
