      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.},
