  1. We present measurements of nonlinear Thomson scattering in both emission hemispheres. The asymmetries in these measurements unambiguously confirm for the first time the figure-8 motion of electrons in the average rest frame.

  2. The individual polarization components of nonlinear Thomson scattering arise from the separate dimensions of electron figure-8 motion caused by a linearly polarized laser field. We present the first measurements of nonlinear Thomson scattering in both emission hemispheres. In the electron average rest frame, the shape of the electron figure-8 path is symmetric about the laser polarization dimension. However, the periodic electron velocity is intrinsically asymmetric. The full scattering emission pattern reveals this asymmetry and the direction that electrons move around the figure-8 path.

  3. We present measurements of nonlinear Thomson scattering out the side of an intense laser focus, showing how subtle defects in laser field including spatial chirp imprint on the angular distribution of the scattered light.

  4. We present first measurements of nonlinear Thomson scattering over the entire emission sphere. Inherent asymmetry in electron relativistic figure-8 motion gives different emission patterns in ‘northern’ and ‘southern’ hemispheres (with laser propagating along poles).
