INSIGHT I Spatio-temporal metrology at focus of ultra-short laser pulses
BEAM SHAPING
INSIGHT
Complete 3D metrology at focus for ultra-short lasers
Developed by the CEA and SourceLAB, the INSIGHT system is a breakthrough metrology sensor to be inserted at the attenuated focus of ultra-short laser systems.
It offers full access to the complex E field (amplitude and phase) in space-time/frequency, in the far-field and the near-field.
It is associated to state-of-the-art analysis algorithms to support the experimentalists in finding the good conditions for interaction.
