| contents | We investigate ablation experiments performed by laser-plasma-filament guided electrical discharges at high-voltages of up to 145 kV. The guiding was accomplished via fs-laser-generated plasma filaments across a gap of 201 mm of air onto steel 1.3343 samples. This method combines remote material processing and enables the steering and deflection of high voltage discharges with the ease-of-use of remote laser processing technology. We observe an increase of the per-pulse-(and-discharge)-ablated volume by a factor of 1.67 over an ablation regime when the discharges are not present and up to a factor of 12.5 over the case when neither discharges nor plasma filaments, only a loosely focused laser beam, are present. |
