High frequency beam oscillation keyhole dynamics in laser melting revealed by in-situ x-ray imaging

Beam oscillation is an attractive method to achieve melt pool and microstructure control in laser powder bed additive manufacturing. Here, in-situ X-ray imaging and high-fidelity modeling reveal the unique keyhole dynamics in a kHz laser oscillation mode.
