abstract = {Spatially selective melting of metal materials by laser
irradiation allows for the precise welding as well as the
3Dprinting of complex metal parts. However, the simple
scanning of a conventional Gaussian beam typically resultsin
a melt track with randomly distributed surface features due
to the complex and dynamic behavior of the meltpool. In this
study, the implications of utilizing a dynamically
oscillating energy input on driving melt trackfluctuations
is investigated. Specifically, the laser intensity and/or
intensity distribution is sinusoidally modulatedat different
scan speeds, and the effect of modulation frequency on the
resulting surface features of the melttrack is examined. The
formation of periodically oriented surface features
indicates an evident frequencycoupling between the melt pool
and the modulation frequency. Moreover, such a frequency
coupling becomesmost prominent under a specific modulation
frequency, suggesting resonant behavior. The insights
provided inthis study will enable the development of novel
methods, allowing for the control and/or mitigation of
inherentfluctuations in the melt pool through laser-driven
resonances.},
