Popis: We have experimentally demonstrated ultrafast diagnostics to visualize the laser wakefield acceleration process in a single-shot mode. We measured the Faraday rotation of a probe pulse due to the magnetic field induced by GeV electrons in low-density plasmas. In addition, we improved the temporal resolution of Frequency Domain Streak Camera (FDSC) to ∼10 fs by broadening the bandwidth of the probe beam, enabling visualization of the bubble dynamics. A prototype experiment using the broad bandwidth FDSC was performed.
