Target position stability study. (a) Cylindrical jet: focus depth jitter σ = 3 μm, lateral jitter σ = 10 μm. (b) Planar jet: focus depth jitter σ = 12 μm, lateral jitter σ = 10 μm, distance to nozzle: 10 mm. (c) Probability histogram describing the amount of laser intensity expected to be applied to the jet depending on its lateral positioning jitter. The intensity values are normalized to the maximum intensity, which is deposited in the cylindrical jet in the event of a central hit, while the value 0 corresponds to the case that the jet was entirely outside the laser focus. It was calculated from the overlap of a step-like jet profile and a Gaussian laser focus intensity distribution. The average spatial jitter of the laser focus was 1.5 μm and thus negligible compared to the lateral positioning jitter of the jet.
