The study and control of hypersonic air flow over a geometry or surface is an area of interest in aerodynamic engineering. Previous studies on drag reduction have utilised effects from short pulse lasers, however, the investigation of high energy ultrafast laser pulse deposition in hypersonic flow poses challenges from laser and wind tunnel requirements, and their integration. We present the novel application of an ultrafast Ti:Sapphire laser delivering pulses of 62 fs duration at energies up to 44 mJ on a 7° axisymmetric cone model in Mach 7.0 flow. We discuss laser-facility integration, optical and engineering challenges, and experimental results of parameterised characterisation of flow modification.
