We demonstrate real-time depth profiling of ultrafast micro-machining of stainless steel at scan rates of 46 kHz. The broad bandwidth and high power of the light source allows for simultaneous machining and coaxial Fourier-domain interferometric imaging of the ablation surface with depth resolutions of 6 μm. Since the same light is used to machine as to probe, spatial and temporal synchronization are automatic.
