Abstract

We present a direct measurement of the nanoscale dynamics of plasma mirrors using wavefront measurement techniques. This two-dimensional measurement, performed via pump-probe diagnostics, enables the reconstruction of the three-dimensional plasma mirror surface with nanometer axial, micrometer transverse, and femtosecond temporal resolution.
